Magnetic resonance and spin dynamics in radical ion pairs: Pulsed time-resolved fluorescence detected magnetic resonance
- Chemistry Division, Argonne National Laboratory, Argonne, Illinois 60439 (United States)
Pulsed time-resolved fluorescence detected magnetic resonance (FDMR) was applied to examine spin dynamics in radical ion pairs. Two time-domain FDMR phenomena were examined; microwave-induced quantum beats and the formation of the ``echo`` signal. These experiments demonstrate the fast decay of the first-order coherence generated by a microwave field on the time scale of 0.05--1 {mu}s. This decay originates through the phase relaxation in the triplet manifold of the pairs and is probably caused by electron dipole--dipole interaction of radical ions in spurs. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
