Abstract:
The rotational spectrum of the 36S-bearing isotopologue of hydrogen
sulfide (H2S) has been investigated for the first time in the
167GHz-1.6THz frequency range, thus providing an accurate and reliable
set of spectroscopic parameters. The experimental investigation was
backed up by state-of-the-art quantum-chemical calculations, which
also allowed us to demonstrate the incorrectness of the previously
reported spectroscopic constants. The present results are of suitable
accuracy to attempt the astrophysical detection of the isotopic
species under consideration. Finally, reliable predictions for the
spectroscopic constants of other rare isotopologues of H2S, namely
the mono- and bi-deuterated species containing 33S and 34S, are
provided.
