abstract = {We have evaluated quantum chemical methods for the
calculation of C-13 NMR chemical shifts in
2-aminobenzothiazole (ABT), 2-(methylamino)benzothiazole
(MABT) and the reaction product from ABT with benzoic acid,
important species in a variety of applications. While using
the BLYP DFT method, the GIAO and CSGT methods to compute
chemical shifts performed very similar for all three
molecules, whereas the LORG methods seem to lead to a
discrepancy. PW91 performs similarly, while MP2 leads to
unsatisfactory results. The empirical ACD program yields
very good absolute values for the NMR shifts compared to the
ab initio calculated results, but gives a significant error
for one of the carbons in the adduct studied. As a
consequence, the well-performing quantum methods are
preferred for unambiguous and correct assignment. (C) 2004
