Abstract

The He I photoelectron (PE) spectra of stilbene (1), 2,2'-dichlorostilbene
(2) 2-amino-2'-chlorostilbene (3), 2,2'-diaminostilbene
(4) ,and 2,2'-dinitrostilbene (5), all in their trans configuration are
recorded and discussed. The electronic structure of 1-5 can well
be described on the basis of the composite molecule method and
simple Hiickel molecular orbital (HMO) calculations. Results indicate
the importance of substituent effects causing characteristic
shifts of low energy electronic band systems in the PE spectra.
