Abstract
A molecular beam of trimethylamine was photodissociated at 193 nm and both the time‐of‐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 time‐of‐flight distribution is well represented by a statistical distribution of unimolecular decomposition. The averaged translation energy was 13% of available energy. The photodissociation of trimethylamine at 193 nm is shown to be dissociative through the hot ground state.
