Abstract
The relaxation of highly vibrationally excited cycloheptatriene molecules by a variety -of added gases has been studied photochemically. The following mean energies removed per downward step were deduced; He, 1.8; No, 2.4; Ar, 3.5; Kr, 3.6; Xe, 3.3; H2, 2.6; D2, 2.4; n-C5H12, 11.7; neo-C5H12, 10.2 kJ mol-1. These agree better with data from the ‘fall off’ of unimolecular reactions than with chemical activation studies.Keywords
