Abstract
A newly constructed Fourier transform microwave spectrometer has been used to record the pure rotational spectra of four isotopomers of SrS (88Sr32S, 87Sr32S, 86Sr32S, and 88Sr34S) between 6 and 26 GHz. The molecules were produced by reacting laser ablated strontium with carbonyl sulfide (0.1% in argon). Pure rotational transitions in the ground, first and second vibrational states have been observed. The data set has enabled a multi-isotopomer fit. Born-Oppenheimer breakdown terms for both atoms have been determined. The 87Sr nuclear quadrupole coupling constant in 87Sr32S has been determined for the first time.
