Notes:
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 C1—C4 hydrocarbons - alkanes, alkenes and alkynes. The formation of organosulfur ions is found in reactions in OCS/hydrocarbon (Cn) mixtures with n 〈4. Formation of organosulfur ions is observed from hydrocarbon ions reacting with OCS and [OCS]+· and S+· reacting with the hydrocarbons. The proton affinity of OCS has been determined to be 688.7±8 kJ mol-1 while that of CS2 is measured to be 712.1±8 kJ mol-1. Comparison with the proton affinity of CO2 shows that the proton affinity increases as sulfur is substituted for oxygen.
