INDUCING COHERENT OSCILLATIONS IN THE ELECTRON-TRANSFER DYNAMICS OF ASTRONGLY DISSIPATIVE SYSTEM WITH PULSED MONOCHROMATIC LIGHT

Calculations are presented that suggest coherent oscillations in the e lectronic state populations of an electron transfer reaction in a pola r solvent can be induced by subjecting the system to a sequence of mon ochromatic laser pulses on the picosecond time scale. These oscillatio ns are produced by pumping the system between different steady state d istributions attained in the presence and absence of a strong continuo us-wave electric field. The amplitude and rise time of these time-depe ndent oscillations may be altered by changing the pulse duration and t he electric field strength. The experimental realization of the propos ed scheme will require strong electric fields (approximate to 10(7) V/ cm), and the effect will be most pronounced for activationless reactio ns.
