Experimental Confirmations
The basic principles of the NEW spin exchange paradigm have been successfully confirmed experimentally.
The obtained experimental results of EPR measurements for nitroxyl radicals confirm the theoretical prediction of the dependence of the frequencies of resonant transitions on the microwave power in the presence of mutual transfer of spin coherence between interacting spins.
