Early broadline NMR and crystal structure

BROADLINE AND PULSED NMR OF IRRADIATED POLYMERS 2.1. Early broadline NMR and crystal structure 

The earliest studies of the changes to the NMR spectrum of irradiated polymers were reported by Sohma et alP and Tutiya and Yamamoto. Of particular interest are the studies of Tutiya of the irradiation of poly(tetrafluoroethylene) (PTFE) at a range of temperatures. - The F NMR spectrum of unirradiated
