Dynamic structural effects and ultrafast biomolecular kinetics in photoinduced charge transfer reactions. Three year progress report, March 15, 1991--May 14, 1994

The reactions were primarily electron-transfer-reactivity related (ET?). Goals were to obtain complete, multimode, experimental descriptions of vibrational (Franck-Condon) barriers to intramolecular electron transfer, explore molecular generality of time-dependent scattering analysis, connect the information directly to measured rates of photoinduced ET (femtosecond, picosecond, nanosecond regime), obtain complementary information in the microsecond regime (longer-range thermal ET) via pulsed-accelrated flow, explore valence localization/delocalization via vibronic coupling (resonance Raman in extended near infrared) and via reversible external manipulation of internal electronic structure, and manipulate and accelerate bimolecular photoredox processes by using room-temperature supercritical fluids. Fe and Ru complexes with such compounds as cyano-N-methylpyridinium compounds were studied.
