A simple method of calculating an energy-spectrum from isothermal measurements, using Fourier techniques

Abstract

A new method is presented to derive the spectrum of activation energies from isothermal measurements. When the integral describing the experimental data is written in a suitable form, a Fourier analysis of the relevant functions leads to an easy solution of the problem. The method turns out to be a very rapid and efficient one, in which the number of data points processed in the analysis can be made very large. The energy resolution of the calculated spectra is not limited by the method of calculation, but only by the finite number of data points and by the experimental errors on them.
