Molecular rotational spectroscopy is a very powerful tool to shed light on the formation
mechanisms of the Universe as we know it, and ultimately to the processes that originated life. After a brief introduction about the basic principles and tools of molecular spectroscopy, focusing in particular on rotational effects, some laboratory techniques to create, acquire and analyze rotational spectra of molecules will be discussed. Special attention will be devoted to the study of reactive species, such as positive and negative ions, and radicals. In the last part of the talk, we will move to space and show how millimeter and sub-millimeter astronomy help to explore and understand the different environments of our local Universe. Finally, pushing the limit of our investigations outside our galaxy we can use the information hidden in molecular species also to test fundamental physical and cosmological models.
