Evaluation of parameters from thermal desorption spectra - Methods borrowed from the analysis of thermoluminescence

A number of methods for extracting the activation energy, pre-exponential factor and reaction order associated with the Polanyi-Wigner rate formulation have been reported in the literature. An entirely analogous equation had been utilized in the study of thermoluminescence (TL) and several methods have been developed for the extraction of the relevant parameters. Some of these methods are practically identical to those developed for the study of thermal desorption, whereas others have not been developed for thermal desorption but can be used with only very minor adjustment to the analysis of thermal desorption curves. In the present work, the utilization of the methods developed for the analysis of TL for the study of thermal desorption data is advocated.
