ESR spectra for -irradiated, at –196 °C, solution of Me2NH, Me3N, and EtNH2 in CFCl3 /0.05÷100% amine/ have been studied. Radical cations Me2NH+., Me3N+. and EtNH
2+.
were trapped in dilute solutions /less than 1% amine in CFCl3/. The yields of radical cations decrease and those of neutral radicals /Me2 N, CH2NMe2, Et NH/ correspondingly increase as the amine concentration increases. Radical cations Me2NH+. are transformed to Me2 N as well as Me3N+. to C H2NMe2 via proton transfer reaction, which is described by the
reaction volume
model.
