Abstract

Rotational transitions of the isotopomers of HCS+ in their ground vibrational states were observed in laboratory and the frequencies were measured in the millimeter- and submillimeter-wave range of 72-396 GHz. The rotational constant B0 was determined to be 18018.262(3), 20444.495(3), and 20991.572(4) MHz, and the centrifugal distortion constant D0, was determined to be 14.56(2), 19.83(3), and 20.82(3) kHz for DCS+, H13CS+, and HC34S+, respectively, with the 3 σ deviations in parentheses. The substitution bond lengths of HCS+ were derived to be rs(HC) = 1.0789 Å and rs(CS) = 1.4782 Å.
