From high-resolution solid-state lSC NMR spectra for the enol forms of some diketones, an average chemical shift of the carbonyl and enol carbons in dimedone is found to move remarkably downfield compared with the corresponding shift in DMSO~/6, which is ascribed to a strong intermolecular hydrogen

The inΓ‘uence of hydrogen bonding (HB) on the 13C chemical shift tensors in four solid amino acids was studied by the ab initio gauge-included atomic orbital (GIAO) approach. The results of the present calculations were compared with those predicted previously and with the experimentally observed shi
