Rotational spectroscopy of isotopic oxirane, $c$-C${}_2$H${}_4$O

Holger S. P. Müller, Jean-Claude Guillemin, Frank Lewen +1

We studied the rotational spectrum of oxirane in a sample of natural isotopic composition in selected regions between 158 GHz and 1093 GHz. Investigations of the isotopologs with o…
