Perturbation Calculation of Spin Densities in π-Electron Radicals

Ferromagnetic spin-delocalized electron donors for multifunctional materials: π-conjugated benzotriazinyl radicals.

We have developed new synthetic methodology for benzotriazinyl radicals that exhibit spin delocalization, low oxidation potentials, and ferromagnetic interactions in the solid state via π-π interactions, making them promising candidates for multifunctional magnetic materials.

π+π− Atom in Chiral Perturbation Theory

Hadronic π+π− atom is studied in the relativistic perturbative approach based on the Bethe-Salpeter equation. The general expression for the atom lifetime is derived. Lowest-order corrections to the relativistic Deser-type formula for the atom lifetime are evaluated within the Chiral Perturbation Theory.

Electron Spin Resonance of Fluorinated Benzophenone Anion Radicals

Bei einer Absorption von 10% des Primärlichts durch die dotierte Schicht werden 90% der Fluoreszenzintensität der reinen Schicht beobachtet, entsprechend z. B. bei 20% Absorption noch 80%. Die Messung zeigt also (nach Abzug des in der dotierten Schicht absorbierten Anregungslichts) mit und ohne K2 dieselbe Fluoreszenzausbeute. Es liegt Fall (2) oder (5) vor. Aus den Diffusionsmessungen dieser A...

Electron Spin Resonance Spectra of Aliphatic Nitrile Radicals

A method which has been widely used to study the electron spin resonance (ESR) spectra of transient free radicals in solution is the continuous flow technique, which was first used in investigating peroxidase-substrate oxidations1. The technique was d e v e l o p e d b y DIXON a n d N O R M A N 2 , w h o a l l o w e d aqueous acidic solutions of titanous chloride and hydrogen peroxide to mix im...
