Quantitative UV-Visible Diffuse Reflectance Spectroscopy of Solid Powders

T. H. Flint, Edward A. Boudreaux

Abstract

In spite of difficulties in attaining high resolution, the determination of UV-VIS-NIR spectra via diffuse reflectance spectro-scopic measurements on solid powders; provides several advantages. Compounds which are difficult to obtain as suitable single crystals, or are found to be unstable or insoluble in liquid solution, can only be studied by diffuse reflectance spectroscopy. Also, since no solvents are required, any effects due to solvation are eliminated. However, it is not possible to resolve the observed spectrum into its anisotropic components, as in the case of single crystal spectra.
