Abstract: We use the gauge invariant atomic orbitals(GIAO) approach,to carry out the ab initio-CHF 13C nuclear shielding calaulations for solid glycine and lysine,and found a better locally dense basis set which is applicable to larger amino acids. The ab initio shielding results are in agreement with the experimental 13C shieldings.

Key words: Glycine, Lysine, Nuclear shielding, Ab initio
