LINESHAPE STUDIES BY FOURIER-TRANSFORM SPECTROMETRY IN FRANCE

A wide variety of remote sensing experiments utilize IR absorption spe ctroscopy to deduce parameters of interest. Inversion of the data is o ften accomplished by comparing the observed spectrum with a synthetic one. Of course the accuracy of the inversion strongly depends on the a ccuracy of various molecular parameters: frequencies, intensities and collisional lineshapes. This paper reviews some recent studies develop ed in various French laboratories and is devoted to cases in which imp ortant deviations from the usual Lorentzian profile have been observed by Fourier Transform spectrometry.
