α,α′-二氧代烯酮环二硫代缩酮类化合物的特征红外光谱(Ⅲ)

The Characteristic Infrared Spectra of α,α′-dioxoketene Cyclic Dithioacetals

研究了 5种α ,α′ 二氧代烯酮环二硫代缩酮类化合物的羰基、碳碳双键、碳硫等一些特征红外光谱 ,尤其着重研究了在共轭体系下的各种特征谱带随化学结构而变化的规律。

The characteristic infrared spectra of the five α,α′ dioxoketene cyclic dithioacetals such as carbonyl,double bond of carbon and carbon,single bond of carbon and sulfur etc have been studied.It is specially important that the changing rules with the change of chemical structure have been discussed.
