It has recently been argued [1,2] that the barrier to rotation around the C À C bond in ethane is not to be explained by the generally accepted picture of steric hindrance between vicinal CÀH bonds in the eclipsed conformation but is caused by more favorable orbital interaction in the staggered conf
