Table 1(b). The values of the chirality Cσ =
[(e1σ∙dr)max]CCW- [(e1σ∙dr)max]CW,bond-flexing Fσ =
[(e2σ∙dr)max]CCW- [(e2σ∙dr)max]CWand bond-anharmonicity Aσ =
[(e3σ∙dr)max]CCW- [(e3σ∙dr)max]CWof the torsional C1-N7 BCP for the isotopomers of glycine are
presented, also see Table 1(a) , all entries are multiplied by
103. The stereoisomeric excess Xσ is
defined as the ratio of the magnitude of the Cσ values
of the S and R stereoisomers of the torsional C1-N7 BCP .
