Abstract : The mobility studies on 14N labeled TEMPOL, carboxy PROXYL, carbamoyl PROXYL in pure water, pure water and glycerol at ratio (15:85) was carried out using 300 MHz ESR spectrometer. The ESR parameters such as linewidth, signal intensity ratio and correlation time were determined. The isotropic g‐factor and hyperfine coupling constant were also estimated. This ESR study reveals that the dipolar and spin exchange interactions are less in the 14N labeled TEMPOL radical. This phenomenon can be explained in terms of the structural, physical and chemical properties of the TEMPOL molecule. The mobility of TEMPOL radical is not much affected by the high viscous medium. Hence the TEMPOL radical can be used as a good spin probe in high viscous medium.
