Abstract
A pre-resonance Raman study of the yellow β-quinol/SO2 clathrate has been carried out using 609.8, 586.8, 514.5, 488.0 and 457.9 run excitation. Pre-resonance enhancement is observed for the guest vl (Al) band at 1147 cm−1 and the host band at 1257 cm−1. These observations are consistent with a charge transfer interaction arising from the LUMO of S02 (S 3pz) and the HOMO of quinol, which consists mainly of the ring π electrons.
