The Raman spectra (2000 to $10cm-1$ 0 of gaseous, liquid and solid oxalyl chloride, $(CCIO)2$ have been recorded and the Raman spectrum of the liquid with qualitative depolarization values have been obtained. In addition to the six symmetry permitted Raman lines for the {trans} conformer, there are eight more Raman Lines observed in the spectrum of the gas (ten for the liquid) which must be assigned to a second conformer. These data have been interpreted on the basis of a more stable {trans} rotamer and a high energy {gauche} conformer in equilibrium for the fluid phases. Assignments are provided for most of the fundamentals for the {gauche} conformer.
