本文报道十一种联苯甲酸类化合物的核磁共振氢谱,其中八种是由超导核磁共振仪作的。超导核磁共振氢谱使环上质子间的多重偶合所形成的复杂裂分简并,图谱简化。有利于联苯环系质子化学位移的解析。结合使用“双照射”记谱,对环上每一质子的归属都能作出合理的解释。但80兆核磁共振氢谱无法作到。本文所报道的十一种联苯甲酸的核磁共振氢谱均未见文献报道。 This paper reports the 1H NMR spectra of eleven biphenylcarboxylic acids, of which eight are made by superconducting NMR. The superconducting nuclear magnetic resonance (1H-NMR) spectrum degenerates the complex fissures formed by multiple couplings of protons in the ring, simplifying the map. Conducive to biphenyl ring proton chemical shift analysis. In combination with the “double exposure” notation, a reasonable explanation of the ownership of each proton on the ring can be made. However, 80 megabits nuclear magnetic resonance spectroscopy can not be done. The 1H-NMR spectra of eleven biphenylcarboxylic acids reported in this paper have not been reported in the literature.
