ls involving rotation about a CC double bond were found to be within the NMR time scale. Activation energies for the above process were determined from variable temperature NMRstudies. The effects of various structural parameters on the energy barrier for isomerization were investigated and the contribution of the vinylic methylthio group to the above barrier was estimated. Internal H-bonding was
