Özet
The interaction of magnesium hydrate at the phosphate oxygen atoms of the purine nucleotides (AMP, GMP, IMP) were studied at the Hartree-Fock level Theory. We used LANL2DZ basis set for Mg and 6-31g* basis set for other atoms. The basis set superposition error (BSSE) begins to converge for used method/basis set. NBO calculations were performed to the second-order; perturbative estimates of donor-acceptor (bonding-antibonding) interactions have been done. The gauge-invariant atomic orbital (GIAO) method was employed to calculate isotropic atomic shielding of the nucleotides using HF/6-31g** level.
