We surveyed the circumnuclear disk of the Seyfert galaxy NGC 1068 between the frequencies 86.2 and 115.6 GHz, and identified 17 different molecules. Using a time and depth dependent chemical model we reproduced the observational results, and show that the column densities of most of the species are better reproduced if the cold gas is heavily pervaded by a high cosmic ray ionization rate of about 1,000 times that of the Milky Way. We discuss how molecules in the NGC 1068 nucleus may be influenced by this external radiation, as well as by UV radiation fields.
