Current State of the Theory of Spin Chemistry: The Spin Chemistry Paradigm

Bulletin of the Russian Academy of Sciences: Physics
Abstract Current problems of the theory of spin chemistry are briefly reviewed. The prospects for practical applications of spin chemistry achievements are discussed. It is shown that in chemical kinetics, it is necessary to consider the possibility of changes in the electron multiplicity of reactants during elementary chemical

Single-electron spin resonance detection by microwave photon counting

Nature, 2023
Spectroscopic measurements of individual rare-earth ion electron spins are performed by detecting their microwave fluorescence, with the method coming close to practical single-electron spin resonance at millikelvin temperatures.

Spin‐free quantum chemistry. XIII. Spin waves

International Journal of Quantum Chemistry, 1973
AbstractWe have obtained the Bloch spin wave dispersion formula using the methods of spin‐free quantum chemistry. The spin‐free eigenvectors are waves in spin‐free space. This development makes the point that Bloch spin waves are dynamically spin‐free. The neutron diffraction transition moment for spin waves is calculated employing the antisymmetrized ...

Spin‐free quantum chemistry. XVI. Spin correlation

International Journal of Quantum Chemistry, 1975
AbstractWe discuss the calculation of quasielastic critical neutron scattering for systems defined by a spin‐free Hamiltonian. The system dependent property which determines the critical scattering is the thermal average of a spin‐free operator called the general unpaired electron correlation operator.

Physics and chemistry of spin labels

Quarterly Reviews of Biophysics, 1970
Biological systems provide the physical chemist with an abundance of interesting, challenging and significant problems. One example is the problem of the molecular basis of co-operative or allosteric interactions between distant ligand or substrate binding sites in hemoglobin and in enzymes.
