The variation in torsional angles for a model linear epoxy system was studied as a function of applied stress and temperature. It was found that all of the torsional angles demonstrate a population migration from a lower to a higher energy state upon the application of an external stress. Subtle changes in torsional angle values under these conditions result in large energy differences.
