摘要：

The spectra and relaxation of CN radicals are studied by FTIR absorption and emission spectroscopy. The relaxation of excited A 2PI vibrational levels proceeds via efficient intramolecular internal conversion processes between the A 2PI and X 2SIGMA levels. The intensity distribution in the observed vibrational CN fluorescence is explained by the occurrence of rapid intermolecular vibrational energy transfer and ''ladder climbing'' processes. The effect of isotopic substitution and medium effects on the relaxation dynamics are also discussed.
