Laser induced fluorescence and high resolution Fourier transform spectrometry

Abstract Laser induced fluorescence was first used in conjunction with a high resolution Fourier transform interferometer to study molecular spectra in the early 1980s. Typical examples of such work are cited in this paper to illustrate the high capabilities of this technique. We have focused on comprehensive spectroscopic analyses (I 2 , double minimum 1 Σ u + state of Na 2 , BaCl, CuCl 2 ), molecular long range behaviour (I 2 , CsH, Li 2 ), hyperfine structure and collisional rate relaxations (I 2 ), large variation of the electronic transition moment (I 2 ), rate determination in an electronic collisional energy transfer (Li 2 ) and time resolved high resolution Fourier transform spectroscopy.
