Viscosity and free energy dependence of photochemical charge separation
Journal of Physical Chemistry A. 101: (1) 25-30, 1997.
Abstract:
Contrary to the conventional (''exponential'') model of contact
charge creation and recombination, we consider here a recombination of a
geminate ion pair occurring in a remote rectangular spherical layer. This
simple model available for analytical solution enables one to
discriminate between inner and outer generation of charges with respect
to a thin recombination layer. In the slow diffusion limit, the
qualitatively different viscosity and free energy dependencies of
effective recombination rate are predicted for these alternative cases.
The experimental verification of these predictions can provide clear
evidence of noncontact electron transfer in liquid solutions.
