Studies of πBonding Characteristics of Nitrile Compound by NMR Spectroscopic Techniques-Evidence of Negative Hyperconjugation
碩士 === 國立成功大學 === 化學系 === 88 === We have measured the values of nitrogen-14 quadrupole coupling constants (QCC), employing NMR relaxation techniques, for a designed series of para-substituted benzonitrile derivatives. It is found that for substituents bearing lone-paired electrons result...
