A detailed computational study of possible ″b 2 ion structures derived by nominal elimination of neutral glycine from deprotonated triglycine along with the structures and energies of the corresponding neutrals has been carried out. These computations of structures and energies have been carried out at the RHF/3-21G, RHF/6-31G(d), B3LYP/6-31G(d), B3LYP/6-31+G(d), MP2(fc)/6-31G(d) and MP2(fc)/6-31+G(d)...
