Abstract: We point out that the “master plot” [ R. Richert, J. Chem. Phys.123, 154502 (2005) ] obtained by normalizing the dielectric loss ε″ by the dielectric relaxation strength Δε is inappropriate because Δε is neither accurately measured when its value is small, nor the high frequency relaxation contribution is eliminated from it. A reliable analysis for change in the distribution of times with temperature is performed by normalizing ε″ by its peak value in the spectra.
