โœฆ Synopsis

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 solvent polarity. The temperature quenching of indole's fluorescence in various solvents has also been investigated and results explained by the dissociation of the exciplex.
