Transcendence of generalized lorentz-lorenz relation in refractometry: statistical incidences

Abstract

The well-known Lorentz-Lorenz relation is currently used in several branches of Optics and Materials Properties for understanding the behaviour of materials and gases under the presence of light. However, this relation was obtained under the assumption of an ideal system. Although, the virial coefficients were introduced to solve this limitation, a new scope has been considered by us, which introduces the molecules physical dimensions and their shape into the Lorentz-Lorenz relation, achieving a generalized form of that L-Lrelation. In this study, the statistical analysis of refractivity versus pressure for Ar, Ne and N data was performed, in order to explore the asymmetry in the statistical distributions in relation to their molecular shape and gas interactions.
