Abstract
The design of an improved infrared reflection–absorption cell which facilitates the study of redox‐active chemical species is described. The modifications to existing cell designs permit (i) the sample to be cooled to temperatures limited by the characteristics of the solvent, (ii) the sample to be maintained under an inert atmosphere, (iii) the study of small (1–2‐cm3) volumes of solution, and (iv) the entire optical path to be maintained under vacuum. These features of the cell design facilitate the study of small quantities of compounds which are unstable with respect to reaction with oxygen, moisture, and redox partners. The study of tris‐maleonitriledithiolato complexes of chromium in formal oxidation states iv, v, and vi demonstrates the advantages of the cell.Keywords
