Spin-controlled atom–ion chemistry

Advent of spin chemistry

In 1976, Atkins 1) wrote a short review entitled “Magnetic field effects” and described at its beginning “The study of the effect of magnetic fields on chemical reactions has long been a romping ground for charlatans”. Until then, so many papers had reported magnetic field effects (MFEs) on chemical and biological reactions. Almost all of such results, however, lacked reproducibility and/or the...

Recent advances in spin chemistry*

The great success in controlling chemical reactivity by spin manipulation was achieved in the last decade, and many remarkable spin and magnetic phenomena have been discovered. Among those discoveries, the most chemically important highlights are magnetic isotope effect, spin catalysis, and single-spin tunneling spectroscopy. This paper summarizes recent advances in these new and hot areas of m...

Spin Chemistry: Coherent Spin Dynamics Rules Chemical Reactions

It is a great honor to edit a special issue of Applied Magnetic Resonance, in particular if the area presented is not magnetic resonance spectroscopy itself. The topic of this special issue, spin chemistry [1], can be considered as upspring of magnetic resonance spectroscopy. On the other hand, the field of spin chemistry contributed significantly to the methodological improvement of both NMR a...

Spin Contamination in Inorganic Chemistry Calculations

An overview of spin contamination and its relationship to broken-symmetry wave functions are presented. Spinoperator expectation-value formulas are developed for use with generalized, unrestricted, and restricted spin orbitals. Currentprojection techniques are reviewed and illustrated for a variety of current theoretical methods.
