Abstract : The positive ion-molecule reactions of OCS have been investigated in an ion cyclotron resonance spectrometer. A variety of reactions in OCS/hydrocarbon mixtures have been investigated for C1-C4 hydrocarbons which are alkanes, alkenes and alkynes. The formation of organosulfur ions is found in reactions in OCS/hydrocarbon (Cn) mixtures with n4. Formation of organo-sulfur ions is observed from hydrocarbon ions reacting with OCS and OCS+ and S+ reacting with the hydrocarbons. The proton affinty of OCS has been determined to be 168 + or - 5 kcal/mol while that of CS2 is measured to be 179 + or - kcal/mol. Comparison with the proton affinity of CO2 shows that the proton affinity increases as sulfur is substitued for oxygen. (Author)
