The spectrum of CO2 has been recorded in the 2 μm region using high resolution Fourier transform spectroscopy. The effective constants have been determined with good accuracy for the (2001, 0401) and (211l, 0511) triads and the 0112–0000 transition. In addition, the vibrational energy of the (3001, 0601)1V level, previously given, has been corrected. The Coriolis resonance, strongly perturbing the (211e1, 051e1)m and (4000, 0800)n levels, has been studied.

Abstract The infrared spectrum of diazirine has been recorded at Doppler resolution with a high informa­tion Fourier transform spectrometer. The ν3 fundamental has been reinvestigated and the overall assignment of the rovibrational transitions has been carried out. From the least-squares analysis a more accurate set of molecular constants including the sextic centrifugal distortion constants has been determined for the level υ3 = 1 and will be reported here. The higher resolution achieved here allowed the assignment of weaker lines and many Q branch transitions. Moreover many blended lines have now been resolved and could be properly assigned.

Laser-excited fluorescence spectra of 128Te2 were studied by high-resolution Fourier transform spectroscopy, the sources of excitation used were Ar+ and Kr+ laser lines at 5145, 4880, 4579, and 4131 Å. (1 Å = 10−10 m). Transitions involving three upper states, [Formula: see text] and [Formula: see text] and three lower states [Formula: see text] and [Formula: see text] have been identified. The molecular constants of the lower states were determined with high precision. These constants were used to obtain the Rydberg–Klein–Rees potential curves of the states for vibrational levels ν up to 42. Limited results were also obtained for the upper states [Formula: see text] and [Formula: see text]

The A1Σ+u − X1Σ+g and B1Πu − X1Σ+g systems of Na2 were excited by Ar+ and Kr+ lasers ranging from 4762 to 6471 Å . High-resolution Fourier transform spectroscopy has been used to analyze the observed spectrum. The study led to the calculation of the molecular constants of the upper A1Σ+u and B1Πu states

The spectrum of CO2 has been recorded in the 1.4–1.7 μm atmospheric window using the very high resolution Fourier transform spectrometer of the Meudon Observatory. This laboratory study has allowed the accurate determination of the spectroscopic constants previously evaluated from the Venus spectrum.

High resolution spectra of Jupiter and Saturn were obtained with a Fourier Transform Michelson interferometer. A comparison of the observed spectra, after elimination of the solar and terrestrial contributions to absorption, with synthetic profiles for the reflecting layer model has permitted new determinations of the Lorentz half-width, the methane abundance, the rotational temperature and the pressure at the level of formation of the methane lines for both Jupiter and Saturn.
