Dielectric constants and pair interactions in polar molecules

Intermolecular interactions effect the physical properties of polar substances to varying degrees. One property for which there exists the possibility of separating out the various components of this interaction (pairs, triplets, etc.) is the total molar polarization of a substance. These effects are quite dependent upon temperature and pressure, so if one is going to make measurements over a large range of these variables, one must develop a system that is capable of handling the conditions. Along with this there must be the necessary instrumentation and other apparatus for measuring dielectric constants which define total molar polarization. In this thesis, the theory behind these measurements will be studied along with the necessary equipment. Also, since one molecule which shows very interesting intermolecular effects is hydrogen fluoride, there will be some investigation into the problem in handling such a corrosive material and the preparation of its isotope, deuterium fluoride, for measurements of the effect of isotopic substitution
