摘要：

The lifetimes of ethyl- and tert-butyl benzene are measured in the gas phase and compared with one another and with those in solution. There is a large increase in the nonradiative lifetime upon going to the gas phase. Furthermore, the observed lifetime is found to be 80 ns at low pressures, independent of the substituent, contrary to the results in solution (the α-substitution effect). These results suggest that the α-substitution effect is solvent induced. © 1979.
