Abstract
The possibility of application of linear free energy relationships for stud ying the effects of substituents on the first vertical ionization potential s of amines, I(n(N)), was substantiated. The I(n(N)) values depend on the i nductive, resonance, and polarizability effects of substituents and are als o affected by hyperconjugation. The sigma (+)(R) resonance parameters of su bstituents MR3 (M = Si. Ge, Sri) and CH2SiMe3 bound to the N.+ radical cati on center were calculated for the first time.
