The temperature dependence of the absorbances of IR-absorption bands corresponding to the fundamental, overtones and combination frequences of diphenylcarbinol in the pure liquid phase is presented. The range of temperature taken in this investigation is between 68 and 298°C. Many difficulties have been met with in trying to find a relation connecting the symmetry of the vibrations and the temperature effect on their absorbances. As shown, in the text, the change in the absorbances of the bands and the temperature variation is linear even for the broad bands.
