Abstract

This paper reviews the general features of magnetic resonance spectra specific to the amorphous chalcogenide materials. We discuss the dominant interactions that influence the local bonding structure. We show how to parameterize the interactions and simulate their spectra in frequency space. In contrast to the crystalline phase, the amorphous material exhibits variations in the local bonding structure. We discuss how to account for these variations and compare the resulting frequency space spectra with their crystalline counterparts..
