The Enhancement Effect of Depolarization Ratio in Raman Scattering Induced by Intermolecular Charge-transfer Interactions

Charge-transfer complexes Naphthalene-I₂, Styrene-I₂, azobenzene-I₂, p-xylene-I₂ and Pyridine-Br₂ have been prepared and excited at the resonant absorption freqency of I₂ in Raman scattering. We have observed the enhancement effect of their depolarization ratioes due to the intermolecular complexation between I₂ （or Br₂） and the organic molecules. and the mechanism of this enhancement effect is discussed.
