Abstract

The temperature dependence of the e.s.r. spectra of spin probes - fatty acid derivatives the nitroxyl fragments of which are incorporated into the surface and internal layers of phosphatidyl choline liposomes (T = 180-260 K) and also of a probe in a model ethanol solution (T = 110-220 K) has been measured. Analysis of the spectra yielded information on the nature and frequency of rotation of the nitroxyl fragments - probes. It is shown that in the systems studied the frequency of movement of the probes corresponds to the region of slow movements, i.e. does not exceed 10⁷ sec^-1.
