Resumo
The new paradigm of spin exchange and its manifestations in EPR spectroscopy contain provisions that are fundamentally different from the widespread initial paradigm of spin exchange. The new paradigm of spin exchange in dilute solutions is also of interest as an example of the formation of a coordinated spin coherence motion of an ensemble of spins in a dilute paramagnetic, and this consistency is achieved by random bimolecular collisions of paramagnetic particles, in fact, the «recoil effect» of spin coherence in random collisions of paramagnetic particles. The new paradigm of spin exchange and new protocols for analyzing experimental data will be more widely recognized and used as a tool, for example, to improve the accuracy of detecting the frequency of collisions of substrate molecules with receptors in molecular biology using EPR spectroscopy. The experimental evidence of the fundamental provisions of the new paradigm obtained in the last 2–3 years are discussed.
