Abstract
Metastable fragments produced in the electron impact dissociation of carbonyl sulphide, carbon dioxide and carbon monoxide have been studied by the technique of time-of-flight spectroscopy. Three metastable fragments were identified in the time-of-flight spectra for dissociation of carbonyl sulphide and have been classified as O(5S), S(5S) and CO (a 3 Pi ). From the time-of-flight spectra, the kinetic energy distributions of the fragments have been deduced. The production of CO(a 3 Pi ) from carbonyl sulphide has been compared with its production from carbon dioxide; the production of O(5S) from dissociation of carbonyl sulphide, carbon dioxide and carbon monoxide is also compared.Keywords
