Abstract

Single crystals of three polymorphs of acetonitrile and acetonitrile-d₃ have been grown under pressure in a diamond anvil cell. While still under pressure polarized mid-infrared spectra of these three single crystals have been obtained. In addition, low temperature far-infrared spectra have been recorded for polycrystals of two of the polymorphs. These data have been used to predict likely crystal structures for the three crystalline phases.
