Abstract

We have developed a simple method for determination of discrete relaxation time spectrum from loss modulus data. The method is based on wavelet transform, which is superior to other method such as SA(simulated annealing) and PL (Pade-Laplace method). Our method determines the number of relaxation times (the number of Maxwell modes) automatically in a single step of numerical operation, because the wavelet transform of loss modulus is a series of peaks whose positions indicate the logarithm of relaxation times. The principle and results of the method can be understood as directly as those of spectroscopic analysis such as IR and NMR.
