Degradation of Pyromellitic Dianhydride during XPS Analysis

Abstract

The degradation of Pyromellitic dianhydride (PMDA) under x-ray exposure has been studied by X-ray Photo-electron Spectroscopy (XPS) and Fourier Transform Infrared Absorption Reflection Spectroscopy (FTIRAS). The data indicate cleavage of the anhydride rings and emission of CO and CO2 molecules into the vacuum.
