[EN] This work has shown spin selectivity in electron transfer (ET) of diastereomers of (R,S)-naproxen-(S)-N-methylpyrrolidine and (R,S)-naproxen-(S)-tryptophan dyads. Photoinduced ET in these dyads is interesting because of the still unexplained phe

[EN] The origin of biomolecules in the pre-biological period is still a matter of debate, as is the unclarified nature of the differences in enantiomer properties, especially for the medically important activity of chiral drugs. With regards to the f

[EN] Photoinduced processes with partial (exciplex) and full charge transfer in donor-acceptor systems are of interest because they are frequently used for modeling drug-protein binding. Low field photo-CIDNP (chemically induced dynamic nuclear polar

Peculiarities of magnetic field and spin effects in a three-spin system with regard to the long-distance character of exchange interaction
Autor: Petr A. Purtov, I. M. Magin, Alexander I. Kruppa
Publikováno v: Chemical Physics. 365:80-84
The biradical recombination probability and its field dependence in the presence of a paramagnetic particle was calculated in balance approximation taking into account the extended character of the exchange interaction in the biradical. Previously, t

Modeling magnetic field effects in multispin systems
Autor: Alexander I. Kruppa, I. M. Magin, T.V. Leshina, P. A. Purtov
Publikováno v: Applied Magnetic Resonance. 26:155-170
A model is proposed for calculating magnetic field effects formed in a radical triad composed of a biradical and a paramagnetic particle. To describe the influence of the “third” spin on the spin evolution in a biradical, the electron spin exchan
