Abstract

With continuing breakthroughs in computational chemistry theory and substantial improvement of computation hardware performance, great progresses have been made in recent years in first principle-based prediction of 1H and 13C chemical shifts of organic molecules. Some methods have even been gradually applied for accurate prediction in complex molecular systems. In this paper, a density functional theory-based high-precision on-line chemical shift prediction platform for organic molecules is established, which provides on-line interactive service of chemical shift prediction for molecules with a molecular weight less than 800. The platform accelerates the mapping between nuclear magnetic resonance (NMR) spectra and molecular structures, and provides a powerful tool for efficient assignment of NMR spectra and accurate analysis of organic molecular structure.
