Comparison of state points via the inelastic intensity at fixed reduced energies. a, b Inelastic intensity at fixed reduced energy \(\left( {\tilde \omega = 0.06} \right)\) along isochrones, isotherms and isobars from the spectra in Fig. 2 plotted a as a function of temperature normalized to value at lowest temperature, b as a function of pressure normalized to the value at ambient pressure. c Inelastic intensity for fixed reduced energies for PPE as a function of τα(T, P) for two isotherms, 293 K (squares), 300 K (diamonds), 315 K (triangles) and an isobar (crosses) for the reduced energies \(\tilde \omega\) = 0.02, 0.04, 0.06, 0.08, 0.1 covering more than ten orders of magnitude in relaxation time. All lines are guides for the eye
