The protocol is written in a manner that makes the computation of chemical shifts tractable for chemists who may otherwise have only rudimentary computational experience. To demonstrate the method, we have chosen the analysis of the cis- versus the trans-diastereoisomers of 3-methylcyclohexanol (1-cis versus 1-trans). and ~50 conformers), the protocol requires ~3-6 h of active effort over a 2-week period. and ~20 conformers), this protocol can be completed in ~2 h of active effort over a 2-d period for more complex molecules (e.g., fewer than ~30 non-H atoms or up to ~500 a.m.u. For a typical structure assignment of a small organic molecule (e.g., fewer than ~10 non-H atoms or up to ~180 a.m.u.

The approach involves the following steps: (i) using molecular mechanics calculations (with, e.g., MacroModel) to generate a library of conformers (ii) using density functional theory (DFT) calculations (with, e.g., Gaussian 09) to determine optimal geometry, free energies and chemical shifts for each conformer (iii) determining Boltzmann-weighted proton and carbon chemical shifts and (iv) comparing the computed chemical shifts for two or more candidate structures with experimental data to determine the best fit. sup.13C NMR spectral data and its proper interpretation for the compound of interest is required as a starting point.
