The laser flash excitation and thermal relaxation kinetics of purple membrane is theoretically analyzed using the rate equations of multiple states system. The derived equation indicates that the photoinduced absorbance change is a complex multi-exponential process. This is proved by a flash photolysis experiment using 532 nm, 10 ns laser pulse as pumping source and 632.8 nm CW laser as probing light. Comparison between the experimental fitting result and the theoretical analysis reveals the possibility of the existence of the KL state. (C) 2000 Published by Elsevier Science B.V.
