Fourier transform IR measurement

L. D Esposito of Dlgllabs we have made some Fourier transform IR measurements to complement those on our conventional equipment. These studies on polyethylene compare the bond rupture kinetics due to y-ray damage and mechanical degradation at various temperatures as measured by ESR and IR spectroscopy. 

Fourier transform IR measurements were used to investigate PVDF films which had been irradiated by means of heavy ions (krypton ions) and electrons. Irradiation with krypton ions was carried out in the presence of helium, hydrogen, deuterium and oxygen. Triple bonds were characteristic of krypton ion irradiation. Double bonds (isolated and conjugated) occurred with both types of irradiation but concentrations were higher with the krypton radiation. The results, including the role of oxygen on the chemical modifications, were discussed. 36 refs.
