Cole–Davidson equation
text:
The Cole-Davidson equation is a model used to describe dielectric relaxation in glass-forming liquids. The equation for the complex permittivity is where ε ∞ is the permittivity at the high frequency limit, Δ ε = ε s − ε ∞ where ε s is the static, low frequency permittivity, and τ is the characteristic relaxation time of the medium. The exponent β represents the exponent of the decay of the high frequency wing of the imaginary part, ε ″ ∼ ω − β . The Cole–Davidson equation is a generalization of
