Dispersion models: published formulas and the models fitted to the curated data.

Every model gives the per-particle polarizability as a function of vacuum wavelength (Model); the refractive index at any state follows by Lorentz-Lorenz. Published formulas are defined, with their printed coefficients and any corrections, in the source records’ [[formulas]] entries and built by formulas.

Modules

base	The model interface: polarizability against vacuum wavelength, with a valid range.
compact	Compact infrared terms for the molecular fits (OEP 2).
fitted	The models fitted here, loaded from data/gas/models/fitted/<name>.json.
formulas	Published dispersion formulas, built from the source records.
oscillator	Oscillator-strength (pseudo-spectral) polarizability models.
registry	Every dispersion model of a gas, and the recommended one.
