Abstract
Using the technique of laser‐induced infrared fluorescence, rate constants have been determined for the relaxation at room temperature, (297±3) K, of: (a) HC1(v=1) and HBr(v=1) by HCN and DCN, and (b) HCN(001) by HC1, HBr, DC1, DBr, and DCN. Vibrational‐to‐vibrational (V–V) energy exchange between the H–C (or D–C) stretching mode in HCN (or DCN) and the diatomic’s vibrational mode is not the major channel by which energy is transferred. The results are examined in terms of the formation of hydrogen‐bonded collision complexes in which there is only a restricted transfer of energy from the excited high frequency mode to other degrees of freedom in the complex.Keywords
