The fingerprints of molecules in space
(University of Innsbruck) Physicists at the University of Innsbruck are on the hunt for nitrogen containing molecules in space. Using terahertz spectroscopy, they directly measured two spectral lines for one particular molecule for the first time. The discovered frequencies are characteristic of the amide ion, a negatively charged nitrogen molecule. With the spectral lines now determined, this species can be searched for in space.
