- 中文摘要: 4-Substituted nitrobenzenes, 4-X-C6H4NO2 (where X=-Cl, -Br, -COCH3, -CHO), complexed with methyl benzenes in inert solvent cyclohexane have been studied by PMR spectroscopy. Equilibrium constant and the chemical shift of pure complex were determind through observation of the A2B2 spectrum of ring protons in the electron acceptor compounds. Equilibrium constant and chemical shift of pure complex were evaluated separately on the basis of either chemical shift A or B. Unequal chemical shift of pure complex was obtained and used to discuss the geometry of complex.
