Rm. Minyaev et al., Stabilization of the glycine zwitterionic form by complexation with Na+ and Cl-: an ab initio study, MENDELEEV C, (2), 2000, pp. 43-NIL_1
Ab initio [MP2(full)/6-31G**] calculations predict that the glycine zwitter
ionic form bridged with NaCl is more stable than the isomeric complexes of
the neutral forms.
