Table 2.

The Debye relaxation parameters, ε_s, ε_i, ε_∞, and τ_i, for pure (100%) methanol, ethanol, 1-propanol, 2-propanol, and water are compared to the reported values in Refs. 16, 19, 20, and 39. In the triple Debye models, the values for ε_s, ε₂, and τ₁ are set to the parameters reported in Ref. 16.
