Time-resolved fluorescence detected magnetic resonance (FDMR) is used to observe alkylaminium radicals formed in n-hexane solutions by electron pulse radiolysis.The ease of observation of aminium radical FDMR signals increases with increasing alkyl substitution of the amine solutes.The results are discussed in terms of the ion-molecule reactions, such as proton transfer, which compete with electron-transfer processes, i. e., the electron transfer from solute molecules to n-hexane radical cations and geminate recombination.
