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
The temperature dependence of the triplet state splittings of naphthalene m either durene or diphenyl over 70-310 K shows that the D + E transition is coupled to a 265 cm" internal mode and D -E to both a 593 cm-' internal mode and external modes with a Debye temperature of 133 K.
## Electron spin polarization in the photoescitrd triplet state of tetraphenyl porphyrin was detected at 100Β°K using EPR technique. The zero Iield splitting parameters IDland IEI for the free base porphyrin were found to be 0.0369 ? 0.0005 and 0.0082 ? 0.0005 WI-'. respectively. ## Detection o
