Abstract

Pure rotational transitions of three conformers of epichlorohydrin were observed. Among the three possible conformers expected for this species, spectra of the two chlorine isotopologues, 35Cl and 37Cl, have been detected for the two gauche-conformers, while only the 35Cl isotopologue was detected for the cis-conformer which is much higher in energy. Well resolved chlorine nuclear hyperfine splittings were observed for all the conformers and isotopologues, yielding precisely determined molecular constants.
