Determining the stereochemistry of organic molecules is a long-standing problem, with implications for stereoselective reactions, catalysis, and the structure of natural products. NMR spectroscopy is widely employed to this purpose; however, the interpretation of results is often entrusted to empirical methods or expert systems. Quantum chemical calculations, generally based on density functional theory, provide a reliable framework to predict the relevant parameters (chemical shifts and coupling constants, generally involving H-1 and C-13) of diastereoisomers with useful accuracy. While the approach virtually spans all molecules of interest in organic chemistry, including those that contain heavy atoms, the analysis of results still poses significant challenges.
