Abstract
Polar molecules (such as acetonitrile, cyanoacetylene, acetone, and nitromethane) imbedded in solid inert gas matrices give rise to different types of IR absorption bands in a spectral range where intramolecular vibrations may be excluded, i.e., below 150 cm-1. Phonon bands of Ar, Kr, and Xe are activated in the range below 72 cm-1. Below 90 cm-1 translational ("rattling") and librational modes of monomer molecules relative to the cage of inert gas atoms were observed. Between 80 cm-1 and 130 cm-1 the IR active intermolecular vibrations of antiparallel dimers appear.
