The relaxation rates of the V_(l0),v_(11),3v_(l6) and v_4 eight single vibrational levels of benzene have been studied by using IR-UV double resonance technique for the first time. The relaxation processes for these eight vibrational levels all exhibit a feature of two exponential decay, which correspond to the V-V and V-T energy ralaxation process respectively. As an example the values of κ_(V-V) and κ_(V-T) for 16_1 10_1 level are 0.59±0.05 μs~(-1)Torr~(-1) and 0.023±0.003 μs~(-1) Torr~(-1) respectively.
