    • In doing so this caused the 3-1 bond in the glycine cation to shorten. Future development of MM3 will need to take into account the electronegativity effects that the carboxylic functional group has on the 3-1 bond length.

    • Inspection of substituent constants for ammonium show that it is inductively electron withdrawing, Wilcox and McIntyre have shown that the carboxylate group shows dramatic dependence of σI (ranging from -0.78 to 0.14) on the dielectic constant and dipole moment.

    • The N-Cα-C-O torsion angle deviated by 38.8° for glycine ZQ calculated with a dielectric constant of 1.5. If glycine is packed into a crystal environment, as explained in the Glycine Zwitterion Results/Discussion section, and a dielectric constant of 4.0 is used for a N-Cα-C-O torsion angle deviated by 59.7°.
