✦ Synopsis

The 1 H NMR study of fulleroproline derivative Ac-Fpr-OtBu and its Pro analogue Ac-L-Pro-OtBu over a range of temperatures in toluene-d 8 solution has enabled the comparison of their equilibrium and activation parameters for the trans/cis interconversion around the amide partial double bond.

The molecrilar orbital method PC'IIN is applied 10 eight N-n~ot~osi~bstituted amides. Experimentally known geometric properties are reasoilably predicted by minimization of total energy with respect to molecular geometry. The bame procedure shows that molecular deformations during rotation around t
