Observation of Quantum Coherence for Recurrence Motion of Exciton in Anthracene Dimers in Solution
摘要:
The quantum beat signal associated with recurrence motion of exciton was observed for two types of anthracene dimers connected through a phenyl ring, on femtosecond fluorescence anisotropy decay. The time periods of oscillation were 0.3-0.9 ps, which correspond to exciton interactions of 30-50 cm-1, and the damping time constants (dephasing time) were 0.7-1.0 ps. The results show that the coherent aspect in photochemical processes is observable even in solution at room temperature, if one employs dimers of rigid structures.
