Zur n-π-wechselwirkung im benzalanilin

Zusammenfassung By a simple HMO model which takes into account first order perturbation and includes n-π interaction the π-band positions in the PE spectrum of N-benzylideneaniline are shown to correlate to the calculated orbital energies. The question, if it is possible to apply Koopmans theorem on the assignment problem of the π-bands is discussed in detail in this special case.

Photoelektronenspektroskopische untersuchung von tris(trimethylelement(IV)aminen, -phosphinen, -arsinen und -stibinen

Abstract The PE spectra of [(CH 3 ) 3 Sn] 3 N, [(CH 3 ) 3 E] 3 P (E = C, Si, Sn), [(CH 3 ) 3 Si] 3 As and [(CH 3 ) 3 E] 3 Sb (E = C, S, Ge, Sn) are analyzed. The constant level of the ionization potentials of the n -hybrid orbitals of N, P, As, and Sb, together with changes in the hybridization and interactions with ligand MOs is discussed by qualitative MO investigations.
