Abstract
Procedures for measuring some relaxation parameters of uniformly and nonuniformly broadened systems by the EPR method in a high-temperature approximation are proposed. The theoretical consideration is based on the concept of spin temperature and Provotorov's equations. A trial field is used along with a saturating superhigh-frequency field. The measuring methods for the time of the transverse relaxation T2 in the case of uniform broadening and some relaxation parameters or their combinations in the case of nonuniform broadening are based on measuring the frequency characteristics of the system when the absorption becomes zero at the frequency of the trial field.
