This unstable molecule displays the rotational spectrum of a linear rotor. For the most abundant isotopic species, HllB32S, the rotational and centrifugal distortion constants are Bo= 19,083.006 MHz and Do=21.89 kHz. Complete substitution structures have been evaluated eight different ways from the variety of isotopic species observed. The resulting mean values for the B-H and S-B distances (in angstrom units) are 1.1692 and 1.5994, respectively.

The alkaline earth metal oxides BaO, SrO, and CaO have been produced in a gas phase flow system by the oxidation of the metal vapor, entrained in argon carrier gas, using oxygen or nitrous oxide. Rotational transitions have been measured for the isotopic species 138Ba16O, 88Sr16O, and 40Ca16O in the ground and first excited vibrational states of the X 1Σ electronic state in the region 80–220 GHz. In addition, ground vibrational transitions have been measured for the isotopic species 137Ba16O, 136Ba16O, 135Ba16O, and 87Sr16O, and 86Sr16O. The Dunham constants Y01, Y02, Y11, and Y12 have been determined from these measurements, and the vibrational constants Y10 and Y20 have been calculated. The following equilibrium internuclear distances have been derived: re(BaO) =1.939630(7) Å, re(SrO) =1.919809(95) Å, and re(CaO) =1.822203(68) Å.
High-precision measurements of many millimeter-and submillimeter-wave rotational lines of different isotopic species of lithium fluoride and chloride in four different vibrational states have provided accurate evaluation of their rotational, vibrational, and potential constants.
