Abstract
Drift mobilities of excess electrons in nonpolar molecular hydrocarbons range from values as low as 0.016 cm2/Vs for long chain alkanes1 to 400 cm2/Vs for methane2 Similarly the rates of electron attachment reactions differ considerably from one nonpolar solvent to another.3 To explain the first observation, the existence of two types of states in these liquids is assumed: a conducting state where the electron is quasi-free (qf) and mobile, and a trapped state (tr) where the electron is localized and relatively immobile. The range in mobilities is then attributed to differences in the probability of trapping. Trapping is more likely in n-alkanes and less likely in methane and neopentane, which are symmetrical molecules.
