Conformational energy computations on a derivative and a homo-dipeptide of C"\*"-diethylglycine were performed. In both cases the Nand C-terminal groups are blocked as acetamido and methylamido moieties, respectively. It was found that the C"3"-diethylglycine residues are conformationally restricted
