The patterns of the IE's below about 11 eV in the photoelectron spectra of ZPh3 (Z = N,P,As and Sb) are discussed in terms of geometric energetic and overlap factors. A deep mixing of the lone pair of the heteroatom with the π-system of the benzenic rings is found for the nitrogen derivatives. This mixing decreases on going towards the Sb derivative. The participation of the heteroatom d orbitals in bonding is discussed.
