The first π*←π transition of the benzene single crystal in polarized light

Abstract

The first π*←π transition in the benzene single crystal is investigated at 82 K. Intensities and polarization ratios for both true and false origins in crystal planes (100) and (010) have been measured and rationalized in terms of crystal field perturbation. At liquid nitrogen temperature the origin of the transition is located at 37865 cm-1 (b), 37817 cm-1 (c) and 37807 cm-1(a).
