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。
In this paper, the nuclear magnetic resonance (NMR) and hydrogen spectra of cyclic polyarylate oligomers were reported. The spin lattice relaxation time of carbon and hydrogen was determined. The results of the comparison with the standard spectra of similar materials, the analysis of the spin lattice relaxation time and the calculation of chemical shift substituent effect, peak.
