The lifetime of indole is shortened when benzene is added to a cyclohexane solution. A proposed mechanism is the formation of an exciplex through hydrogen bonding. The finding from the picosecond study presented here shows that the anomalous behavior of indole is not totally determined by the solven

The electron transfer to methylviologen was confi
The picosecond fluorescence lifetime of 4-(N,Ndimethylamino)triphenylphosphine in propanol s&vent was measured at high pressures up to 400 MPa by the method of time-correlated single-photon counting. The fluorescence response curves were well fitted to triple exponential functions monitored at both
