Abstract
Spectral investigations of the structure of the high temperature phase of $C_{2}H_{2}$ and $C_{2}D_{2}$ are in agreement with the proposed $T^{6}_{h}$ space group with 4 molecules/unit cell on $S_{6}$ sites. Raman and new infrared results on the low temperature phase provide support for a $D_{2h}$ orthorhombic structure similar to those of the halogens and carbon disulfide, in which the molecular axis is not coincident with the figure axis of the site.
