The third member of the cumulenethione series, H2CnS, propadienethione, has been produced by pyrolysis of cyclopenteno-1,2,3-thiadiazole and detected by microwave spectroscopy which provided rotational parameters for the 32S and 34S isotopomers, the dipole moment [2.064(8) Debye], and an indication that propadienethione is a planar molecule of C2v symmetry.
