In an effort to deduce the source of the.cttine internalrotation barrier, we have investigated the contributions of exchange energy and orthogonzlity: ti4io effects that are required by the Pauli principle.

Receised 7 February -969 Distortional effects on the barrier to L?p?nal rotation of ethane x-e investigated through ab tnttto calculations. yielding a theoretical barrier of 3.071 kcal/mole (experimental 2.928 kcal/mole). The com-Lwted barrier is 3.064 kcal/moIe ior borazane and 1.44 kcal/mole for m
Sasis sets. Minimum basis set calculations predict the barrier in ethyl fluoride to be 0.5 kcd/mole smaller than the ethzne barrier. Extended basjs set cdcufations give barriers of 3.4 and 3.3 kcal/mole for ethyl fluoride and ethane. These results are in better ;igrecment with the espcrimcntal value
