Experimental and theoretical study of the absolute intensities of the IR bands of cyclopentadiene

The system of electrooptical parameters which characterizes the polarization properties of the bonds of the cyclopentadiene molecule is calculated. The absolute intensities of the IR bands are interpreted.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii Fizika, No. 1, pp. 42–46, January, 1970.The authors thank O. S. Nikitin for assistance in the measurements.
