14^N and 15^Cl nuclear-quadrupole coupling constants in thiazyl chloride from microvawe spectroscopy and ab initio molecular orbital computations

The14N and35Cl nuclear quadrupole coupling constants of the14N32S35Cl isotopic species of thiazyl chloride have been determined from an analysis of the hyperfine structure of six? a and? b transitions in the microwave spectrum as (in MHz) ?aa (35CL) = -39.00(3), ?bb (35CL) = 23.84(4), ?aa (14N) = -1.42(6), ?bb (14N) = -4.16(6).
