Near-resonant vibrational energy transfer from nitrous oxide to benzene

Near-resonant vibration-to-vibration energy transfer from N2O(0001) 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(0001) to the CD stretch and, in N2O–C6H6, the pathway is from N2O(0001) 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.
