β¦ Synopsis
A b initio Hartree-Fock calculations at the 6-31G*//6-31G* and MP3/6-31G*//6-31G* levels of theory are reported for propylamine. All ten stationary points needed in a description of the rotation around the C1-C2 bond have been located on the 6-31G* surface and each of these points has been examined at the MP3 level.

The reaction pathway for the insertion reaction of SnCl into the Pt-Cl 2 Ε½ . Ε½ . bond on the cis-Pt Cl PH compound was investigated at the ab initio MO level of 2 3 2 theory. The optimized structure obtained for the transition state indicates that this reaction proceeds through a three-center transi
## Abstract The barriers to internal rotation about the Cο£ΏN bond in several thiopiperidides have been determined by the NMR technique. It was found that the barrier height (Ξ__G__^β‘^) increases in the series cinnamoylthiopiperididemβand __p__βsubstituted cinnamoylthiopiperidides the barriers were s
