Popis:	It has been shown by UV-spectroscopy in solvents of varying polarity that heteroaromatic N-oxides form molecular complexes of n, π -type with tetracyanoethylene. As time passes they convert into ionized form. The convertion rate increases parallel to donor basicity, solvent polarity and temperature. The formation of equimolar and trimolar complexes has been proved according to the UV-spectroscopic and dipole moment data. Stability constants have been calculated.
