Synthesis, Crystal Structure and Barriers to Racemizacion of N-aryl-4-Pyridones
The He I photoelectron (PE) spectra of stilbene (l), 2, 2'– diclorostilbene (2) 2-amino-2'– chlorostilbene (3). 2, 2'-diaminostilbena (4), and 2, 2'– dinitrostilbene (5), all in their trans confiruration are recorded and discussed. The electronic structure of l-5 can well be described on the basis 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 system in the PE spectra.
