Molar Refractivity - related to pressure


Molar refractivity, A, is a measure of the total polarizability of a mole of a substance and is dependent on the temperature, the index of refraction, and the pressure.

The molar refractivity,in terms of density, is defined as shown after substituting the molar refractivity into the Lorentz-Lorenz formula.
