Abstract

The pure rotational spectrum of BaS (X¹Σ⁺) has been recorded in the frequency range 355-396 GHz using direct absorption methods. Data were recorded for six isotopomers: ¹³⁸Ba³²S, ¹³⁷Ba³²S, ¹³⁶B³²S, ¹³⁵Ba³²S, ¹³⁴Ba³²S, and ¹³⁸Ba³⁴S, in vibrational states ranging from v = 0 to v = 6. This work is an extension of past microwave and millimeter studies. Revised spectroscopic constants have been established for the six species. The dissociation energy for ¹³⁸Ba³²S is estimated to be DEhc∼ 42 392 cm^-1.
