摘要
本文报道了环状聚芳酯低聚物的核磁共振碳谱及氢谱。测定了其碳及氢的自旋晶格弛豫时间,通过与类似物质标准谱图的比较、自旋晶格弛豫时间的分析以及化学位移取代基效应的计算等,归属了其碳氢谱峰。
The 13C-NMR and 1H-NMR spectra were reported for the macrocyclic polyaryl-ester oligomer. The spin-lattice relaxation times for carbons and protons were measured. By comparing with the standard spectra for similar compounds and according to the analysis of the spin-latt:ce relaxation times and the calculation of substitution effect of chemical shifts, the carbon-13 and proton spectra were assigned completely,
