    • At these concentrations, the amount of solvent displaced by solute is very small, and so the diamagnetic correction for the solvent is essentially the same in neat solvent and solution. For an example, see the tables of concentrative properties of aqueous solutions for metal salts in: CRC Handbook of Chemistry and Physics, 60th ed.; Weast, R. C., Astle, M. J., Eds.; CRC Press: Boca Raton, FL. 1980: p D-227.

    • It is also possible to determine -2J from temperature-dependent chemical shift data. See: Cotton, F. A.; Eglin, J. L.; Hong, B.; James, C. A. J. Am. Chem. Soc. 1992, 114, 4915. The solvents used in this study have a limited temperature range and are not optimal for these measurements. In addition, the donor-acceptor interaction between the solvent and animine protons is expected to be temperature dependent.
