Molecular order and dynamics of chlorophyll a triplets in liquid crystals are studied by transient ESR following pulsed laser excitation. The time evolution of the transverse magnetization is monitored at various static and microwave magnetic fields. Analysis ofthc ESR transients isachicved by emplo

Time-resolved EPR spectra were first observed for the lowest excited triplet state of metallophthalocyanines ( MPc: M = 2Na, Mg, and Zn) in a rigid glassy matrix at 77 K. The zero-field splitting 1 D 1 parameters are smaller compared with those of metalloporphyrins. Introduction of the Zn atom to PC
The time evolution of the spin-polarized transient EPR signals of the radical pair state P&Q; is studied in perdeuterated reaction centers of Rhodobacter sphaeroides R-26 in which the non-heme iron has been replaced by zinc. The transients show modulations of the signal amplitude on several time sca
