Production and microwave spectra of dithioformic acid, HCSSH

Publikation: Bidrag til tidsskriftTidsskriftartikelForskningfagfællebedømt

Hitherto unknown dithioformic acid, HCSSH, has been produced by pyrolysis (300°C) of methanetrithiol, HC(SH)3, and identified by the microwave spectrum (18-40 GHz) of its most abundant species H12C32S32SH. Rotational transitions of this species in its ground state have been assigned to a trans and a cis rotamer. Both rotamers are planar, the trans conformer being the more stable by ca. 350 cm-1 mole-1. For each rotamer spectra of molecules in two vibrationally excited states have been assigned. Frequencies of transitions of importance for search for HCSSH in interstellar space are reported.
