Equation describing the time-dependence of a relaxation time that deviates from an Arrhenius-type temperature dependence. \[\tau = \tau_{0} \exp\!\left({\frac{B}{T - T_{0}}}\right)\] \(\tau\)/\(\pu{s}\) = relaxation time; \(\tau_{0}\)/\(\pu{s}\) = relaxation time at the Kauzmann temperature, \(B\)/\(\pu{K}\) = constant; \(T\)/\(\pu{K}\) = temperature; \(T_{0}\)/\(\pu{K}\) = Kauzmann temperature.
