title: [Study on spectroscopy of alpha, alpha'-dioxoketene cyclic s, s-acetals].
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.
