Sažetak
The slow molecular motion of several deuterated and undeuterated spin probes differing in size and shape, embedded in a model glycerol-water matrix, have been studied by double-modulated electron spin resonance (DMESR). The DMESR spectra as a function of temperature reveal two motional regions. From the experimental linewidths of both deuterated and undeuterated spin probes in the lower temperature region and simulated data based on the variation of T1 relaxation, two different dynamics of the -CH3 groups attached to piperidine ring were resolved. Our results indicate that the onset of the whole spin probe motion depends on the type of probe and the matrix density.
