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 various Cl-C4 hydrocarbonsallranes, alkenes and alkynes. The formation of organosulfur ions is found in reactions in OCS/hydrocarbon (C,,) mixtures with n t 4 . Formation of organosulfur ions is observed from hydrocarbon ions reacting with OCS and [OCS]" and S" reacting with the hydrocarbons. The proton atfinity of OCS has been determined to be 688.7 * 8 kJ mol-' while that of CS, is measured to be 712.1 f 8 kJ mol-l. Comparison with the proton affinity of C02 shows that the proton affinity increases as sulfur is substituted for oxygen.
