Abstract

Crystalline powders, when pressed into plates at pressures of about 40,000 pounds in.⁻², reflect strongly in the infra-red spectrum at wave-lengths characteristic of their functional groups. This points to usefulness of such plates in optical investigations of any materials not available as large crystals.
