From an analysis of the widths of the hyperfine lines in the ESR spectrum of a nitroxidelabelled polystyrene in toluene solution, the correlation times for rotational diffusion at three temperatures have been measured. The values agree well with published data from NMR studies of polystyrene in solu
The intramolecular (segmental) mobilities of poly(vinylpyrrolidone) and poly(vinylcaprolactam) in solutions have been investigated using the spin label technique. The rotational correlation times for the segments do not depend on the spin label used for their determination. The rotational correlatio
