Abstract : A thin layer spectroelectrochemical cell for use with aqueous or organic solvent systems is described and evaluated. The cell design, comprising a working chamber formed by sandwiching Teflon spacers between two optical windows and a Teflon body, allows versatility of the working electrode material, and is easily dismantled and reassembled. Variation of the window material permits measurements to be made over a wide spectroscopic range, from the uv visible to the infrared regions. The performance of the cell is assessed for a gold minigrid working electrode in the uv-visible region using the oxidation of 2,9,16,23-tetra(neopentoxy)-phthalocyaninato zinc to its pi-cation radical in o-dichlorobenzene, and in the infrared region by investigating the reductions of bis(2,2'-bipyridine)(2,2'-azodpyridine)ruthenium(II) bis(hexafluorophosphate) in deuterated dimenthylsulfoxide.
