CH2OS Carbon monoxide-hydrogen sulfide

In what follows the states of the CO-H2S are labeled by KJKJC where K corresponds to the projection of /, the total angular momentum, onto the intermolecular axis, and is written E for K= ) (II forAT=l, and so on). mean the asymmetric-rotor labels for the correlated H2S free rotor states

The microwave spectrum could be assigned to the pora-species Eqoo ( h = 1) and to the ortho-species Eioi (7h = 0). Tunnelling splittings, caused by the interchange of the bonded and non-bonded hydrogen nuclei of the H2S subunit, were observed and analyzed.
