- Hydrogen bond mediated NMR J couplings offer additional structural information. The interpretation of these usually small hJ couplings are,however, not necessarily straightforward. In the present case of a carbohydrate system, a four-bond classical W coupling, 4JHO4,H5, is morereasonable on the basis of, in particular, density functional theory calculations of spin-spin coupling constants at the UB3LYP/6-311G** levelof theory.
