The back-electron transfer (b-ET) process in the hexamethylbenzene/tetracyanoethylene charge-transfer complex was studied by the transient absorption spectroscopy in several fluids (ethane, nitrous oxide, carbon dioxide, and trifluoromethane) from the critical density to twice of it at 323. 2 K. The b-ET rate increased with increasing the solvent density, and also increased in the order of ethane, nitrous oxide, carbon dioxide and trifluoromethane, compared at the similar reduced density divided by the solvent critical density. The b-ET rates in various fluids were well correlated with the theoretical b-ET rates estimated from the analysis of the absorption spectra based on the formulation by Marcus and Jortner.
