ROTATING DISK CELL FOR RAMAN SPECTROELECTROCHEMISTRY: INVESTIGATION OF AN ELECTRODE SURFACE SPECIES AND AN ELECTROGENERATED SOLUTION SPECIES.

A Raman spectroelectrochemical cell has been developed which incorporates a rotating disk design. This cell has been shown to be useful for the Raman investigation of electrode surface species (spinning electrode) and electrogenerated solution species (static electrode). It has been used to characterize the Raman spectroelectrochemical behavior of photolabile dithizone anion adsorbed at silver and copper electrode surfaces. Use of this cell for the study of electrogenerated solution species was demonstrated by the resonance Raman characterization of the tetracyanoethylene anion radical electrogenerated with a cyclic potential step. Cell construction is described and its merits discussed.
