Abstract

Many photoinduced electron transfer reactions are accompanied by nuclear rearrangements of the molecules involved. In order to understand the reactivities of the molecules and the reaction mechanisms, precise information on the molecular structural changes accompanying the electron transfer is often required. We present here conventional XAFS and transient energy dispersive XAFS studies on (1) the structures of excited and photoinduced charge separated states of porphyrin and porphyrin based supermolecules, and (2) structures of Ti02 colloid and the heavy metal ions that bind to the colloid surfaces during photocatalytic reductions.
