Abstract
Infrared spectra of HCN and DCN in Ar, $N_{2}$ and CO matrices at $4^{\circ} K$ and $20^{\circ} K$ have been studied in the range from 4000-50 $cm^{-1}$. A detailed study of the effects of concentration and diffusion on the absorption bands of both isotopes are utilized to elucidate the structure of the various hydrogen-bonded aggregates. Both temperature and environment variations indicate that the dimer is probably linear or very nearly so and that the crystal field splits the degenerate modes of vibration. The results of calculations of hydrogen bond extensions, force constants, frequencies of lower lying vibrations, and hydrogen-bond energies of a variety of species in the $C-H\cdots N$ system using the Lippincott-Schroeder potential will be discussed.
