✦ Synopsis
An integrated CaF, crystal optically transparent infrared (ir) thin-layer cell was designed and constructed without using any soluble adhesive materials. It is suitable for both aqueous and nonaqueous systems, and can be used not only in ir but also in uv-uis studies. Excellent electrochemical and spectroelecrochemicai responses were obtained in evaluating this cell by cyclic voitammetry and steady-state potential step measurements for both ir and uu-uis s~tro~~tr~hemist~ with ferri/ferrocyanide in aqueous solution, and with ferro~ne/ferr~nium in organic solvent as the testing species, respectively. The newly designed ir cell was applied to investigate the electrochemical reduction process of bilirubin in situ, which provided direct information for identifying the structure of the reduction product and proposing the reaction mechanism.
