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(<sup>5</sup>S), S(<sup>5</sup>S) and CO (a <sup>3</sup> Pi ). From the time-of-flight spectra, the kinetic energy distributions of the fragments have been deduced. The production of CO(a <sup>3</sup> Pi ) from carbonyl sulphide has been compared with its production from carbon dioxide; the production of O(<sup>5</sup>S) from dissociation of carbonyl sulphide, carbon dioxide and carbon monoxide is also compared.
