GEM is a research laboratory at the University of Valladolid focused on the characterisation of the structures of biomolecules and molecules of astrophysical interest using rotational spectroscopy in combination with different techniques for vaporization. 

Since 2012 our group is a Unit Associated to CSIC involved in an international endeavor to advance our molecular understanding of the universe. Together with laboratories in Spain, Europe and the United States (NASA), we are using high resolution experimental techniques to produce and analyze important possible inter-stellar molecules to meet the needs of the astrochemical and astrobiological community.
