The ionization potentials of a number of meta and para substituted benzyl radicals were determinned by electron irapact. The substituents, in order of decreasing ioaization potential of the radical, were m-CN, m-NO/sub 2/, p-CN, m-F, p-Cl, p-F, p-i-Pr, and p-CH/sub 3/O. The resuits are in agreement with the known electron-releasing or electron-attract ing powers of the substitusnts. Since the effect of the substituents on the stabllity of the radicals themselves is very small, ths resuits permit a consideration of the stabilization of ions in the gas phase where solvation plays no role.
