The barriers to rotation of RCH2 groups (R = Me, Et and Isopr) as 3-substituents in 4-Me-δ4-thiazoline-2-thiones, their 4-t-Bu analogues, and the methiodides of the latter compounds have been studied by 1H DNMR and by molecular mechanics calculations. The barriers in the 4-t-Bu compounds are rather insensitive to the size of R, which is shown to be caused by strain in the ground state. More generally, it is shown that when δG
