Abstract:	The first vertical ionization potentials of isostructural P(III) and As(III) compounds EX₃ (E = P, As) whose highest occupied molecular orbital is preferentially localized on the lone electron pairs of atom E depend on the inductive, resonance, and polarization effects of substituents X. Hyperconjugation in fragments like As⁺^·-C-H is the only resonance effect in radical cations As⁺^·X₃. The same effect in similar P-centered radical cations is weaker.
