Title: Raman and far infrared spectra of crystalline acetylene, $C_2H_2$ and $C_2D_2$
Abstract: Raman and far infrared spectra of the orthorhombic and cubic phases of acetylene and deuterated acetylene have been obtained. In the orthorhombic phase, three of the four expected librations have been identified in the Raman spectrum and the two infrared active translations have been confirmed, for both samples. In the cubic phase, two of the three predicted librations in the Raman spectrum and the expected pair of translations in the far infrared spectrum have been observed, again for both samples. Splittings in the internal mode Raman spectra are, with one exception, in agreement with the predictions of group theory.
