Resumen:

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-L
relation. 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.

Resumen divulgativo:

Se propone un nuevo alcance para la relación de Lorentz-Lorenz con el fin de considerar las dimensiones físicas de las moléculas y su forma.Estos resultados son especialmente interesantes para dispositivos de refractometría: interferómetros Fabry-Perot de modo único y mediciones de dispersión de luz.

Palabras clave: Statistical distributions, phyisic-chemicals properties, virial coefficientes, Lorentz-Lorenz relation.
