A dynamic longitudinal internal conductivity model, derived from the classical method of moments, is applied to the analysis of recent simulation data and reflectivity measurements of shock‐compressed dense xenon plasmas. This model satisfies both the non‐zero f –sum rule and the second non‐zero sum rule, and reproduces the non‐monotonicity of the conductivity of dense plasmas beyond the domain of applicability of the Drude‐Lorentz model.
