Abstract
The microwave torsional‐rotational spectra of CH2DSH and CHD2SH have been measured and analyzed over the frequency range 12.5–48.0 MHz. a‐, b‐, and c‐dipole transitions have been assigned for both species which makes it possible to determine the tunneling frequency between the two gauche torsional levels for both species. An internal rotation analysis gives the torsional potential energy coefficients V1=−3.40±0.10 cm−1, V3=456.3±0.5 cm−1 for CH2DSH and V1=4.45±0.10 cm−1, V3=424.5±0.5 cm−1 for CHD2SH with V2 constrained to zero.Keywords
