Chapter Two deals wit,h polarisatwn and polari~. ahilit,y, the Clsusii~s-Yfc,ssotlim d Debye eqltations, n a h r refrnr,tion and polarisation, and the dipole moment. The following r:hapter s,~mmariaesin some detail the relation of dipole moments t,o molec~tlar structure, inclucling the estimntirm of ionic ~chmseter,bond m d gl.oup moment-, deduction of stmatures, and ii~trarnolecr~lar rotation. Chapter Four diarusses the failure of the I k h y e eqia~tiorr in polar solvenh, eoncenlrated solutions and pure liquids. The Onsager treatment and some of its modifiralians, problems eneountercd in hydrogen-bonded liq$~ids nrld the treatment by Kirkwood are dewrihed. The fifth chapter covers dielectric: dispersion, and opens wilh :I disn~ssionof dielectric loss, ph:~se, rungle and the complex permitt,ivity.

The final chapter considers intermolecular fr,rcs and ~nergier.
