Spectral surveys provide the only way to determine the full molecular inventory of an object and hence build a comprehensive view of the state of the molecular gas and its role in star formation and the structure and evolution of the ISM. Of course spectral surveys also provide the most efficient method of identifying new and unexpected species that have to be include in the chemical networks. The most extensive and complete survey of an extragalactic system has been the continuous spectral survey from 129 GHz to 175 GHz carried out by Martín et al. (2006) toward NGC253. This first spectral line surveys at 2 mm towards the prototypical starbursts galaxies NGC253 have shown an unexpected chemical richness.
Due to the limitations of observing at a single atmospheric window, missing maybe part of the material that will affect the chemistry, our next step has been to extend the extragalactic spectral line survey of NGC253. Using the APEX telescope we have extend the survey to higher frequencies and carried out the first spectral line survey of an AGN nucleus like NGC4945, and a close ULIRG, ARP220. Those Surveys allow as to get better estimates on the physical and chemical characteristics of the three galaxies, as well to search for better tracers to study the star-formation in those distant objects, with different physical characteristics. We present here the three spectral surveys together with some new observations of several anions and dense tracers observed in a larger sample of galaxies, covering more types of galaxies, i.e. seyfert.
