1. Organic compounds with an increasing degree of conjugation were synthesized and investigated by the EPR method: difurylpolyene ketones, difurylpolyene diketones, and also products of the condensation of the diketones ...

The EPR allowing a direct observation of supertransferred hyperfine fields on the nuclei of the next-nearest cations to copper ion in the structure of LaSrGa0.995Cu0.005O4 isomorphous to the superconducting cuprates prove ...
