Summary:
The purpose of this research is to investigate the electronic structure of propylene. The vacuum-ultraviolet absorption and magnetic circular dichroism (MCD) spectra of propylene were obtained by Professor Snyder at the National Synchrotron Radiation Center. The absorption and MCD spectra are presented in the region 52 000--77 000 cm-1. The spectra were examined in detail in the pi → pi* region from 52 000 cm-1 to 58766 cm-1. The MCD provides unique information about the electronic structure of a molecule. The MCD spectrum clearly showed that there are at least three electronic transitions in the pi → pi* region of the propylene spectrum. The presently proposed assignments for these transitions are pi → 3s, pi → pi*, and pi → 3p. The first step in the vibrational analysis, which may aid in the assignments of the electronic transitions, was carried out. A theoretical calculation of the normal vibrational modes of ethylene and propylene has been done using Hyperchem software.
