Abstract:

Pulsed EEDOR experiments using optical detection have been developed and utilized to study spectral diffusion within the inhomogeneously broadened zerofield spin transition of a photoexcited triplet molecule. Two distinct spectral diffusion processes have been observed. One is very fast and is the source of the rapid loss of spin coherence previously observed in spin echo experiments of photoexcited triplet molecules. This rapid spectral diffusion seems to be limited to a narrow range of frequencies within the inhomogeneous profile of the spin transition. The second phase is considerably slower, but can sample a greater range of frequencies within the inhomogeneous profile. This second spin diffusion process determines the minimum hole width which can be observed in a steady state EEDOR experiment. Author
