Authors: Melen, F.; Sauval, A. J.; Grevesse, N.; Farmer, C. B.; Servais, Ch.; Delbouille, L.; Roland, G. Bibcode: 1995JMoSp.174..490M Altcode: The solar spectrum offered the opportunity to discover OH lines with high rotational quantum numbers, which do not appear on laboratory spectra. On solar absorption spectra, the authors have identified about 580 lines, among which about 400 were observed for the first time. They belong to pure rotational transitions in the ground state (υ = 0→3; Jmax″= 48.5), as well as to the (1-0), (2-1), and (3-2) vibration-rotation bands (Jmax″= 32.5). Previous pure rotation, vibration-rotation, and Λ-doubling data sets related to the υ = 0 up to 3 levels were fitted simultaneously together with this new set of data, in order to obtain a very complete and accurate set of molecular constants for the X2Π ground state.

J.; Marché, P.; Karcher, F.; Amoudei, M.; Dufour, B. Bibcode: 1987P&SS...35..665Z Altcode: Within the context of the MAP/GLOBUS campaign of September 1983, several trace species have been observed by absorption spectroscopy at the two ground stations of the Jungfraujoch, Switzerland (3580 m altitude) and the Observatoire de Haute-Provence, France (1905 m altitude). The results obtained for HCl and for HF, expressed in terms of mean integrated columns above these sites are: Jungfraujoch: (2.1 ± 0.2) E15 mol cm -2 HCl (4.8 ± 0.2) E14 mol cm -2 HF Haute-Provence: (2.6 ± 0.2) E15 mol cm -2 HCl. Taking into account the difference in the altitude of the two stations, the reported HC1 results are in agreement to within their respective uncertainties. The integrated column density of HCl and HF above 11 km altitude, deduced from airplane observations on 9 September 1983, are: (1.65 ± 0.25) E15 mol cm -2 HCl above 11 km (3.7 ± 1.7) E14 mol cm -2 HF above 10 km supporting satisfactorily the ground measurements. Title: The nickel spectrum in the infrared - Application to the solar spectrum Authors: Biemont, E.; Delbouille, L.; Roland, G.; Brault, J. W. Bibcode: 1986A&AS...65...21B Altcode: The spectrum emitted from a nickel hollow cathode has been recorded in the infrared region (1800 < σ < 9000 cm-1) with the National Solar Observatory Fourier transform spectrometer. The spectra have been used in order to identify many lines on new high resolution solar spectra. Title: Fourier transform spectrographs. Authors: Delbouille, Luc Bibcode: 1986ESOC...24..119D Altcode: 1986vlt..work..119D Fourier-transform spectrograph (FTS) configurations for the ESO Very Large Telescope (VLT) are discussed. The advantages of FTSs over grating spectrographs are reviewed, including large throughput, minimum line distortion, photometric accuracy, wavelength calibration, instrumental flexibility, and the 'multiplex' advantage; the application of state-of-the-art array detectors to FTSs is also considered. A scaled-up version of the FTS for the 4-m Mayall telescope at KPNO (Hall et al., 1979), with a 2-m-focal-length collimator and 30-cm cat's-eye retroreflectors, is briefly characterized. It is suggested that such an FTS be evaluated as a preliminary design for the VLT instrument. Title: Identification on chromium lines in the infrared solar spectrum based on new interferometric measurements Authors: Biemont, E.; Delbouille, L.; Roland, G.; Brault, J. W. Bibcode: 1985A&AS...61..185B Altcode: High resolution spectra of chromium obtained by the interferometric method show the presence of several hundreds of new lines in the infrared region (1800 < V < 9000 cm-1). These spectra have been used in order to proceed to the identification of many weak lines on the high resolution solar spectra obtained recently by Delbouille et al. (1981). Title: An investigation of iron in the infrared solar spectrum based on FTS laboratory measurements Authors: Biemont, E.; Roland, G.; Delbouille, L.; Brault, J. W. Bibcode: 1985A&AS...61..107B Altcode: The application of new high-resolution laboratory data for iron, covering the region 1800 to 9000/cm, to the identification of many weak lines on high signal-to-noise-ratio solar photospheric spectra, is discussed. The spectra emitted by iron hollow cathodes with three different carrier gases (He-Ne-Ar) are recorded with the Fourier transform spectrometer on Kitt Peak. Comparisons between the spectra of iron and the spectra of nickel and of chromium recorded with the same carrier gas and between the iron spectrum and the KPNO solar spectrum drawn at the same scale are considered. The results are presented in tables. Title: The Interest of Simultaneous Spectral and Spatial High Resolution Spectroscopy in the Infrared Authors: Delbouille, L.; Grevesse, N.; Sauval, A. J. Bibcode: 1985LNP...233..108D Altcode: 1985hrsp.proc..108D Up to the present, small scale structures on the sun have mostly been studied through observations made in the visible and ultraviolet. After having recalled some of the main advantages of infrared observations, the authors give a few samples of high spectral resolution/low noise solar spectra now routinely obtained in this spectral range by using Fourier transform spectrometers. The authors then show that such high spectral resolution spectra could be obtained in short period of time and for small scale solar structures, using a LEST type collector.

Title: Infrared bands of C2 in the solar photospheric spectrum Authors: Brault, J. W.; Testerman, L.; Grevesse, N.; Sauval, A. J.; Delbouille, L.; Roland, G. Bibcode: 1982A&A...108..201B Altcode: Lines of the C2 Phillips system have been successfully searched for on new tracings of high resolution solar spectra. From a rather large number of lines of the (0,0), (1,0), and (0, 1) bands, we derive empirical values for the band oscillator strengths: f00 = 1.41 10-3, f10 = 1.38 10-3, and f01 = 1.12 10-3. These solar f-values are discussed in section 3.1 and compared with recent laboratory data.

For the Ballik-Ramsay system, only a few unblended solar lines have been available, from which we deduced 0.6 10-3 ≪ f00 ≪ 1.2 10-3. Title: f-values for Tb ii and a search for terbium in the solar photosphere Authors: Biemont, E.; Roland, G.; Delbouille, L. Bibcode: 1981SoPh...71..223B Altcode: Oscillator strengths have been obtained for the first time for 12 transitions of Tb II. Solar implications based on these f-values and on recent hyperfine structure data are discussed. More especially, a detailed investigation of a weak absorption feature located around λ 3658 is presented.

Bibcode: 1977GeoRL...4..117Z Altcode: Infrared solar observations made by balloon at 27.9 km altitude in April 1976, and from the ground station of the Jungfraujoch, Switzerland, in October 1976, have confirmed the presence of hydrofluoric acid in the upper stratosphere. An average value of (3.6 ± .7) × 10-10 ppv has been deduced for the concentration of HF above 27.9 km. The comparison between the ground-and the balloon observations tends to indicate that over 50% of the total atmospheric HF is located above 25 km altitude. Title: Book reviews Authors: Reijnen, G. C.

Bibcode: 1969RSPTA.264..171D Altcode: The University of Liege has operated, since 1958, a laboratory of solar spectroscopy at the International Scientific Station of the Jungfraujoch (Switzerland). During recent years, much effort has been devoted in two main directions: (a) techniques of correction for the effects of the instrumental function to obtain the best possible knowledge of central intensities and profiles of photospheric lines; (b) increase of the signal to noise ratio in the records in order to detect and measure very faint absorption features. In addition, a balloon-borne equipment is now under construction in Liege to observe, with maximum resolution, the near infrared solar spectrum from an altitude of about 80 000 ft. Title: Project to Map the Sky in the Infrared from an E.S.R.O. Satellite Authors: Delbouille, L. Bibcode: 1969RSPTA.264..319D Altcode: One of the experiments installed in the TD 1 E.S.R.O. satellite (expected launching date 1970), will be devoted to a mapping of the sky in the lead sulphide region. The scanning will be obtained by the motion of the satellite itself, so a relatively simple infrared photometer will be used.

Bibcode: 1967ApJ...147..697H Altcode: The XX38743875 A region of the solar spectrum is re-examined for the occurrence of lines of the 0-0 band of the ultraviolet system of the C13N isotopic molecule. Although the well-known solar line X3874 341 A is in excellent wavelength agreement with the P(58) line measured in the laboratory, the P(57) line that should also occur in a window in the solar spectrum is found to be absent. It is, therefore, concluded that the wavelength agreement in the case of the F(58) line is spurious and that no lines of C11N are observed. From this, a lower limit R 40 for the C12/C13 abundance ratio in the photosphere is obtained. Title: A New Determination of the 12C/13C Abundance Ratio in the Solar Photosphere. Authors: Delbouille, L.; Herzberg, Luise; Roland, G. Bibcode: 1966AJ.....71Q.383D Altcode: There are at present in the literature two different values for the photo spheric abundance ratio 12C/13C, derived from different interpretations of the 3874 A region of the solar spectrum. This region, as Greenstein, Richardson, and Schwarzschild (Publ. Astron. Soc. Pacific 62, 15, 1950) have suggested, is the only region where there are suitable windows for the observation of lines of C13N [P(58), A3874.345A and P(57), A3874.922 A of the 0,0 ultraviolet band]. Greenstein et al. could not detect lines of 13CN, and from their absence and the fact that in the windows the solar centinuum is approached within 3 % derived a lower limit R=36 for the 12C/13C ratio. In contrast, Righini (Liege Colloq. 1956, p. 265; Ric. Sci. Rev. 3, 145, 1963) obtained R=104 on the assumption that the known weak 3874.358 A Zr+ line is blended with the 13CN, P (58) line. Correction of a trivial error in the equivalent width reduces his value to 10~, leaving a discrepancy by more than a factor 10 between the results. We have re-examined the question with solar spectra of higher resolution than obtained before, and with new laboratory spectra kindly provided by A. E. Douglas. We confirm the coincidence of the P (58) 13CN line with the Zr+ line at x3874.358 A. However, near the predicted position of the P (57) line A3874.923 A we find only one new line at A3874.99 A. The wavelength difference of 0.07 A is too large for identification of this line as 13CN. We therefore conclude that the coincidence between the solar line at 3874.358 A and the 13CN, P(58) line is spurious, and that even the new high-resolution spectra do not show lines of 13CN. From this we arrive at a lower limit R 40, essentially confirming the value of Greenstein et al.
