Infrared absorption spectra of various dibenzo-p-dioxin derivatives were measured and a strong characteristic absorption band was found in the region of 1330-1280cm-1, considered to originate in asymmetric stretching vibration of C-O. At the same time, examinations were made on absorption bands for C-H out-of-plane vibration.
