Molecular resonance Raman observation of tetrathiafulvalene oxidation by colloidal platinum crystallites.

Aqueous metal colloids provide a prototype system for understanding the electrode surface chemistry of electrochemical cells. In colloids a high metal:electrolyte surface area is present in an optically homogeneous medium. Small metallic crystallites in liquids have the ability to acquire and store excess negative charge via oxidation of surface adsorbed molecules. In this short manuscript, we explore the oxidation of tetrathiafulvalene by Pt crystallites of ~30angstroms diameter.
