We used the IRAM-30m telescope to observe the central 1.5-2kpc region of NGC 1068, covering the frequencies between 86.2GHz and 115.6GHz. Using Boltzmann diagrams, we calculated the column densities of the detected molecules. We used a chemical model to reproduce the abundances found in the AGN, to determine the origin of each detected species, and to test the influence of UV fields, cosmic rays, and shocks on the ISM. Description: We present the results of a 3mm molecular line survey towards the nucleus of the nearby AGN galaxy NGC1068. We show the final averaged spectrum after eliminating bad scans and subtracting baselines of order 0 or 1 to the individual spectra. Y-axis is in antenna temperature scale.
