Electrochemical reduction of either of two different carbon blacks dispersed in methylene chloride gave rise to a temperature independent narrow ESR signal superimposed upon the characteristic broad signal. The observation of this conduction ESR (CESR) signal implies that there are two distinct envi
Samples of P33 carbon black, heat treated in the range 1600"-26OO"C, were studied by E.P.R. The lineintensity, localized and free spins contributions, and g-factor, are examined as a function of residence time at H.T.T. (a few minutes to several hours). The correlation between the g-factor and diama
Coals of increasing rank contain a mixture of solid fragments and particles which look liquid. The first ones are a fractions insoluble in boiling anthracene-oil, the others are /I fractions (soluble in anthracene-oil but insoluble in toluene). The content of fi fraction passes by a maximum as softe
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
Low density polyethylene was spin-labelled with an oxazolidine-N-oxyl group. Correlation times for the motion of the label were calculated both in the slow-motion region and in the motionallynarrowed region. In the latter situation, the central line shape was successfully simulated. A correlation ma
