Photoelectron spectroscopic studies of the Propyl- and Allyl-substituted amines

Abstract

The HeI (21.22 eV) photoelectron spectra of the mono-, di- and tri- propyl- and allyl-substituted amines are reported up to 21 eV. The assignments are based on SPINDO calculations, on the comparison with other related molecules, a density of states analysis and a sum rule treatment. The first ionization potential band in each of the spectra is assigned to the nitrogen lone-pair electrons and for the allylamines the second band is assigned to the ethylenic π-bond electrons.
