Abstract

Polarized Raman spectra are reported for the lattice vibrational region of single crystals of the diazines: pyrazine, pyrazine-$d_{4}$, pyrimidine and pyrimidine-$d_{4}$. The lattice region for polycrystalline pyridazine has also been investigated. Raman spectra as a function of temperature between approximately $100^{\circ} K$ and $300^{\circ} K$ are reported for all the crystals. Assignments are suggested based on the results of the polarization and deuterium substitution studies.
