Infrared Transmission Spectroscopy with Thin Layer Cells

1 Infrared Transmission Spectroscopy with Thin Layer Cells 

A gold or platinum wire mesh or minigrid acting as the working electrode and located in the beam path, an additional metal grid serving as the counter electrode

These coated glasses can be used as working electrodes [optically transparent electrodes (OTE)] in standard three-electrode arrangements provided that both glass and coating are chemically and electrochemically stable and inert in the used electrolyte solution and the applied range of electrode potentials. The use of a modified infrared spectroscopy transmission cell equipped with quartz windows for UV-Vis spectroelectrochemistry has been described [18]. Platinum layers deposited onto the quartz served as an optically transparent working electrode and an additional platinum layer served as a pseudo-reference electrode. A counter electrode outside the thin layer zone (in one of the tubes used for solution supply) served as a counter...
