ABSTRACT

It was shown, that rate of spin-lattice relaxation EPR signals of ferredoxin in temperature interval 9-22 K is proportional to T5. The mechanism of spin-lattice relaxation of non crystalline systems that explains the experimentally observed strange peculiarities of temperature dependence of relaxation rate, for a number of globular proteins, has been considered.

ABSTRACT

The ESR spectra of animal tissues have been recorded at 13-43 degrees K. The reduction of the ESR signal intensities of the Fe-S proteins have been found in starving mice which is due to the substrate diminishing in these animal tissues.
