摘要
The effect of basis set quality and glycosidic conformation on the calculated chemical shieldings of the C-1 and C-4 glycosidic carbon atoms of some naturally and commercially important model beta-(1 --> 4), alpha-(1 --> 4) and alpha-(1 --> 3) Linkage systems have been investigated using ab initio molecular orbital coupled Hartree-Fock gauge included atomic orbital (CHF-GIAO) methods, The STO-3G, 3-21G, 4-31G and 6-31G** basis sets have been tested in our calculations.
