Evidence for electric field-assisted back-electron transfer through a methylene bond in a linked compound of phenanthrene and phthalimide in a polymer film114(2001); http://dx.doi.org/10.1063/1.1370566View Description Hide Description
Fluorescence emitted from phenanthrene linked to phthalimide by a short methylene chain is unusually enhanced by an electric field in a polymer film. Back-electron transfer which produces the fluorescent state of phenanthrene occurs through a short methylene bond following photoinduced electron transfer from phenanthrene to phthalimide, and its efficiency is enhanced by an electric field.

Photodissociation of impurity-doped solids involving chemical reactions with host atoms is experimentally studied. We demonstrate that the formation of intermediate molecules (HKrCl) plays a central role in the photodissociation of HCl in solid Kr, developing considerably the general understanding of solid-state photolysisdynamics. In addition, these experiments provide a quantitative test for the ab initio calculations of IR absorption intensities of novel rare-gas molecules. The measured UVabsorptionspectrum of HKrCl is valuable for characterizing the electronically excited states of rare-gas containing species, which is a significant challenge to theory.
