摘要：

Novel time-resolved reaction yield detected magnetic resonance studies are reported on exciplex systems consisting of pyrene and dicyanobenzene. It is shown that the fluorescence from the systems, observed under the action of a static and a resonant magnetic field, exhibits a marked variation in time, including oscillations, after the creation of the exciplex. This variation is characteristically different between the three isomers of the dicyanobenzene molecule. In a theoretical analysis, the major experimental features are reproduced and it is suggested that oscillations observed in the fluorescence decay curves may correlate with ST0 mixing quantum beats. This experiment provides a new method for studying the spin evolution inside radical pair systems and for estimating the lifetime of the spin-correlated radical pair.
