the hydroxylated compounds has been studied by high dilution IR spectroscopy. In all of these derivatives, the bulky But group blocks rotation around the C-S bond. The results for these compounds are compared with those reported for their analogous 2-methylthioderivatives. For sulphones and RR/SS sulphoxides, the possible dihedral angle deformations have also been evaluated.
