Abstract

The gas phase photodissociation of the cyclic sulfoxides, (CH₂)_nSO (n equals 2, 3, 4), has been studied following 193 and 248 nm photolysis. The nascent vibrational state distribution of the SO(X³(Sigma) ^-) photofragment following photolysis of each cyclic sulfoxide contains detailed information about the photochemical mechanisms. The SO vibrational state distributions have been measured by laser induced fluorescence spectroscopy on the (B³(Sigma) ^- -- X³(Sigma) ^-) transition, after 193 and 248 nm photodissociation of each cyclic sulfoxide. The observed vibrational state distributions are compared with physical models to help reveal the fragmentation mechanisms.
