No attempt was made to interpret data on the overtone and combination bands or those on asymmetric $C_{2}D_{2}H_{2}$. The interpretation of data on the fundamental bands of the other four isotopes was based on the fact that the derivatives of the electric moment with respect to the symmetry coordinates should be equal for the isotopes. Through this comparison, it was possible to eliminate some of the ambiguity ari\’{s}ing from the uncertainties in sign introduced by taking the square root of the intensities. Values of bond moment and effective charge calculated in this manner are more reliable than those obtained previously and provide the basis for a re-examination of the bondmoment hypothesis. en_US dc.format.extent 99417 bytes dc.format.mimetype image/jpeg dc.language.iso en en_US dc.publisher Ohio State University en_US dc.title THE INFRARED ABSORPTION INTENSITIES OF ETHYLENE AND SOME DEUTERATED ETHYLENES en_US dc.type article en_US
