Abstract
The microwave investigation of propargyl mercaptan has been continued to study the internal rotation of the SH group in the molecule. A Hamiltonian is proposed to describe the over-all rotation and the torsion of the top. The analysis leads to the result that the potential function is a double minimum potential with a lower barrier of 470 ± 10 cm-1 at the eis position and a higher barrier of 2000 ± 500 cm-1 at the trans position.Keywords
