LESR studies of long-lived photogenerated spins in the MX-chain complex, Pd(chxn)2Br3

Light-induced ESR (LESR) measurements have been applied on the halogen-bridged metal complex (MX-chain), Pd(chxn) 2 Br 3 , to study the dynamics of the photogenerated spin such as neutral soliton and polaron. The time evolution of the LESR intensity is interpleted in terms of the pair-creation and recombination model of photogenerated spins which are separated by the finite potential barriers on the chain. The LESR intensity showed the same excitation power dependence with the one in the Pt-Cl compound.
