| 摘 要： | 研究了5种含有苯环取代基的α，α′—二氧代烯酮环二硫代缩酮类化合物的红外光谱的特征吸收规律，指出了这类化合物分子结构对红外吸收谱带的影响；对^1H NMR，^13C NMR共振谱带做了全面的归属。并且讨论了分子结构对^1H NMR，^13C NMR共振谱带化学位移的影响，其变化规律与红外光谱一致，为这类化合物的结构及谱学研究提供了启发性的模式。

| Abstract: | The rule of infrared spectroscopic characteristics of the five alpha, alpha'-dioxoketene cyclic s, s-acetals was studied, and the influence of the molecular structure on the IR was indicated. All 1H and 13C NMR chemical shifts of the five compounds were assigned, and the effects of structures on the chemical shifts of 1H and 13C NMR were discussed. The rule of change is the same as that of IR. The study offers a method of elicitation for studies on the structure and the spectroscopy of this kind of compounds. |
