METHOD OF DETERMINATION OF SATURATION FACTOR OF ELECTRON TRANSITIONS OF PARAMAGNETIC INTERSYSTEM IN SUBSTANCE Russian patent published in 2015 - IPC G01N24/12 

FIELD: instrumentation.

SUBSTANCE: substance containing the paramagnetic system is used, installed in the resonator of double electronic-nuclear resonance of NMR, MRT, DPY spectrometer with pumping circuit at frequency(ies) of electronic resonance and detecting, at frequency(ies) of nuclear resonance, position of nuclear resonance line is determined for substance δ₁ upon application of some power of microwave radiation with non-resonant frequency with electronic transitions of the electronic subsystem, then position of the nuclear resonance line of substance δ₂ is measured upon application of the same power of microwave radiation at resonance frequency with electronic transitions of the electronic subsystem, then displacements of the nuclear resonance lines for substances δ₁ and δ₂ are compared, and required saturation factor is determined from comparison of the measurement results, namely from relative displacement of the nuclear resonance line δ = δ₂-δ₁.

EFFECT: assurance of possibility to measure saturation factor of the electronic transitions in substance samples, containing unpaired electrons, paramagnetic centres and admixtures depending on power and frequency of applied electromagnetic radiation.
