Thermal energy charge transfer reactions of rare-gas ions to methane, ethane, propane, and silane. The importance of franck-condon factors

Thermal energy charge transfer rate constants from He +, Ne +, Ar +, Kr + and XE + to CH 4, CD 4, C 2H 6, C 3H 8 and SiH 4 have been measured using ion-cyclotron resonance spectroscopy. The data are interpreted in terms of a model that presumes the magnitude of the rate constant is directly related...

Summary:Thermal energy charge transfer rate constants from He +, Ne +, Ar +, Kr + and XE + to CH 4, CD 4, C 2H 6, C 3H 8 and SiH 4 have been measured using ion-cyclotron resonance spectroscopy. The data are interpreted in terms of a model that presumes the magnitude of the rate constant is directly related to the magnitude of the Franck-Condon factor connecting the molecular neutral and ion. Addition measurement between N 2O +, CO + 2, CO + and N + 2 charge trans ferring to SiH 4 indicate the ion-neutral collision distorts the Franck-Condon manifold from that appropriate to sudden ionization processes (photon or electron impact).
