Molecular beam photodissociation of trimethylamine

摘要

A molecular beam of trimethylamine was photodissociated at 193 nm and both the timehyphen;ofhyphen;flight and angular distributions of photofragments were measured. The isotropic angular distribution observed indicates that the dissociative lifetime is much longer than the molecular rotation period. The broad timehyphen;ofhyphen;flight distribution is well represented by a statistical distribution of unimolecular decomposition. The averaged translation energy was 13percnt; of available energy. The photodissociation of trimethylamine at 193 nm is shown to be dissociative through the hot ground state.
