14. Another equation, known as KWW function (see Ref. 16 below) is seen as equivalent to the Cole-Davidson (CD) equation. But P. Lunkenheimer, U. Schneider, R. Brand, and A. Loidl, Contemp. Phys. 41, 15 (2000)
15. reported that CD equation described their spectra better than the KWW equation.

20. g used in the analysis should be for liquids of identical purity, and should correspond to a fixed value of relaxation time for all liquids, whether determined from dielectric study or from DSC scans.Difference between the DSC-estimated structural relaxation time and the dielectric relaxation time should be taken into account.
