THE TRANSITION FROM NONADIABATIC TO SOLVENT CONTROLLED ADIABATIC ELECTRON-TRANSFER KINETICS - AN EXPERIMENTAL-STUDY

At sufficiently high temperatures, the solvent longitudinal dielectric relaxation time τL is less than 1 ns; the charge-transfer process converting the S1,CT to S0 of arylaminonaphthalenesulfon-N,N-dimethylamide derivatives is controlled by solvent polarity, while at lower temperatures, τL is more than 1 ns and controls the rate. © 1990.
