Comparative charge-exchange mass spectrometric and argon-sensitized radiolytic studies on methanol

Abstract
It is shown that the formation of CO and CH4 in the argon-sensitized γ-radiolysis of methanol is dependent on a mechanism of charge exchange with the species Ar+. On the other hand, the ion Ar+ 2 formed from Ar* is of minor importance. The formation of CH+ 3 from methanol after charge exchange with Ar+ is a rapid process, taking about 10–13s.
