Abstract :
The technique of principal component analysis has been applied to spectra obtained by thermally stimulated discharge current measurements on polyimide films. The films had been aged by gamma irradiation followed by long term exposure to elevated temperatures. The relationship between the aging history and the changes observed in the principal component values derived from the spectra are discussed.
