Abstract: Pyrazine-d, a crystalline solid at room temperature with a melting point near 55$^{\circ} C$, has been prepared. The Raman spectrum of the melt well above the melting point and the infrared spectrum of the vapor are presented. The molecular symmetry is reduced by the isotopic substitution to $C_{s}$, and the vibrations are all either in-plane or out-of-plane. Those with C type contours in the infrared must have depolarized Raman counterparts, and those with polarized Raman bands must have infrared counterparts that lack the strong central prominence of the typical type C band. Preliminary assignments are given and compared with results of earlier investigations of isotopic pyrazines. The state of polarization of Raman bands of pyrazine and pyrazine-d adsorbed onto aqueous sodium borohydride generated silver sols is discussed.
