The Kirkwoodg(1)factor for room temperature liquid chlorobenzene has been measured from (a) the integrated intensity of the far IR rotationhyphen;translation band, and (b) the long time slopes of the singlehyphen;particle and totalhyphen;particle dipole correlation functions, using the Keyesndash;Kivelson rotational diffusion model. The values are 1.13plusmn;0.11 and 1.18plusmn;0.10, respectively, and do not agree with the Kirkwoodndash;Frohlich theory, which predicts 0.83. The vibrational and far IR band shapes are presented, along with their second moments and the dipole correlation functions. The vibrational band second moment is within experimental error of the theoretical value; the far IR band second moment is in excess by 153percnt;.
