Theoretical calculations of magnesium aspartate-arginine (Mg[Asp-Arg]) structure and spectroscopic characteristics have been performed in the gas phase with the GAUSSIAN 98 software package using density functional theory (DFF) at the B3PW91 level. The 6-31 + G* basis set was selected due to their reasonable quality and size. The comparison with corresponding results for magnesium aspartate-glycine (Mg[Asp-Gly]) is presented. NMR and IR measurements were carried out and obtained experimental H-1 and C-13 chemical shifts and IR spectra are compared with calculated spectral parameters. © 2005 Published by Elsevier B.V.
