Abstract
The spectra and relaxation of CN radicals are studied by FTIR absorpti on and emission spectroscopy. The relaxation of excited A 2PI vibratio nal levels proceeds via efficient intramolecular internal conversion p rocesses between the A 2PI and X 2SIGMA levels. The intensity distribu tion in the observed vibrational CN fluorescence is explained by the o ccurrence of rapid intermolecular vibrational energy transfer and ''la dder climbing'' processes. The effect of isotopic substitution and med ium effects on the relaxation dynamics are also discussed.
