摘要: 40 years have passed since the first molecular detection outside our Galaxy. Since then, knowledge on distribution, kinematics and composition of material in extragalactic ISM has built up significantly based not only carbon monoxide observations but also more than 50 species detected. In particular, line surveys been proven to be excellent tools study chemical nuclei galaxies. Such studies favored by increasing instantaneous bandwidth current mm sub-mm facilities. Here I will summarize highlights spectroscopy, mostly focusing results from published last few as well aims still ongoing projects.
