摘要
The delta(13)C=O chemical shifts and the carbonyl stretching frequencies nu(C=O) are affected by their physical surroundings, and information about the chemical structure can be obtained by study of delta(13)C=O and nu(C=O) in various solvents or solvent systems, Solvent acceptor numbers (AN) are not a precise indicator of delta(13)C=O chemical shifts or nu(C=O) frequencies due to steric factors of both the solute and solvent, which alters the distance between the sites of solute and solvent interaction when the same solvent is used for different solutes of a homologous series.
