摘要:
Gauge including atomic orbitals (GIAO) H-1 NMR chemical shift calculations have been performed for 66 organic compounds at 72 different levels of theory using the multi-standard approach (MSTD) previously developed for C-13 NMR This straightforward computational technique involves the combination of methanol and benzene as standards. The studied methodology has been shown to predict H-1 NMR chemical shifts efficiently at different levels of theory.
