Use of tetracyanoquinodimethane derivatives in electron paramagnetic resonance magnetometry.

摘要

The use, in electron paramagnetic resonance (EPR) magnetometry, of tetracyanoquinodimethane derivatives corresponding to the formula: …… in which AH<+> is a cation derived from a heterocyclic aromatic base containing at least three aromatic rings and a single NH<+> group included in at least one of these rings. …AH<+> is for example acridinium or benzoquinolinium.
