The characteristic infrared spectra of the five alpha,alpha'-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.
