Photodissociation dynamics of ethylene sulfide at 193.3 nm

Article abstract of DOI:10.1063/1.457228

We have investigated the photodissociation dynamics of ethylene sulfide (thiirane) at 193.3 nm by studying Doppler broadened laser induced fluorescence spectra of atomic sulfur fragments.The only dissociative channel found produces S(1D) atoms and ethylene molecules.The measured average translational energy of the fragments is 20.5+/-4.5 kcal/mol.We have found an anisotropy in the velocity distribution of the atomic sulfur fragments (β =1.03+/-0.19 ), which confirms that the 193 nm transition is a parallel transition.We conclude that the dissociation is direct and symmetric, both C-S bonds breaking at once.The dissociation time is estimated to be about 300 fs.
