Photoelectron Spectroscopy of Some trans-2, 2'-Disubstituted Stilbenes
The He I photoelectron (PE) spectra of stilbene (1), 2, 2'-di-chlorostilbene (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 bases of the composite molecule method and simple Hückel molecular orbital (HMO) calculations. Results indicate the importance of substituent effects causing characteristic shifts of low energy electronic band systems in the PE spectra.
