EPR line shifts due to spin exchange of perdeuterated 2,2,6,6-tetramethyl-4-oxopiperidine-1-oxyl (14N−PDT) in aqueous solutions and the same probe isotopically substituted with 15N (15N−PDT) were measured from 293 to 338 and 287 to 353 K, respectively . . .

The sensitivity of the 14N-hyperfine splitting of nitroxide spin to the local electric field, Eloc, has often been used to probe the polarity of microenvironments; however, two uncertainties have been faced at once as follows: (i) the value of Eloc in . . .

EPR spectra of perdeuterated 2,2,6,6-tetramethyl-4-oxopiperidine-1-oxyl (PDT) are studied as functions of molar concentration, c, and temperature, T, in water and 70 wt % glycerol in water. The increase of the intrinsic line width averaged over the th . . .
