The advent of diffuse reflectance (DR) IR spectroscopy as a routine technique has greatly facilitated the study of otherwise intractable solid samples. In particular, research involving coals, catalytic processes, and solidstate photochemical reactions is being carried out by this technique. However, infrared spectra of air-sensitive solid powders are often difficult to measure with conventional DR accessories. For such studies, several vendors of IR accessories (Spectra-Tech, Inc. and BIO-RAD, Inc.) recommend techniques involving the use of an environment chamber. This is a relatively expensive component (103 $) and is more elaborate than instrumen tation required for many routine studies. In an effort to provide a DR cell for routine measurement of hydroxide species in various anhydrous but extremely water-sensitive inorganic salts, we have developed a cell of simple design which fits in sample-cap holders of Spectra-Tech DR accessories.
