Until recently, molecular spectroscopy of extragalactic sources was based on the observation of a few molecules, only. From 1971 to 1980, nine molecular species have been detected, most of these with telescopes operating at cm-wavelengths (see the review of Morris and Rickard, 1982). With the exception of the widely distributed CO, only very little data had been obtained. CO is a tracer of low density molecular gas. To detect gas at higher densities (n(H2)≥ 104 cm—3), to trace its distribution and kinematics, to determine temperatures and to study chemical properties, we set up a project with two main lines of research: (1) We attempted to enlarge the number of detected molecular species and (2) we tried to study some of these in more detail, in order to obtain astrophysically relevant results.
