Hot cores are warm, dense clouds of gas and dust associated with recent high mass star formation. The complex and poorly understood physical and chemical processes occurring in these regions result in the formation of a rich complement of complex molecules. Here we report on the abundances and temperatures derived for many molecular species, including complex organics and nitriles, observed in the rich hot core G327.3-0.6. The data were taken with the Swedish-European Submillimetre Telescope (SEST). Many of these molecules are best described by small (0.02 to 0.03 pc) source sizes and high (\~150 K) temperatures. Some of these molecules do not have viable gas formation routes which could be indicative of an ice mantle origin.
