Near-resonant vibrational energy transfer from nitrous oxide to benzene

Near-resonant vibration-to-vibration energy transfer from N2O(00(0)1) to benzene has been studied by use of the WKB semiclassical procedure in the temperature range of 100-500 K. In N2O-C6D6 the principal energy transfer pathway is found to be from N2O(00(0)1) to the CD stretch and, in N2O-C6H6, the pathway is from N2O(00(0)1) to the overtone CD bending mode, The N2O-C6D6 energy transfer probability is twice that of N2O-C6H6. The temperature dependence of the N2O-C6D6 probability is negative, whereas that of N2O-C6H6 is positive. (C) 1997 Published by Elsevier Science B.V.
