  1. 1.

    We measured the absorption spectra of the solid layers of a number of simple and complex salts of tetracyanoquinodimethane (TCNQ), which layers were obtained by rubbing the substance on a quartz backing, and a comparison was made of these spectra with the spectra of the corresponding salts in acetonitrile solution.

  2. 2.

    The spectra of the solid layers of the simple salts resemble the spectrum of the (TCNQ)2 dimer, which testifies to a predominance of the paired reaction of the TCNQ anion-radicals in the solid state. The spectra of the complex salts have a more diffuse character when compared with the spectra of the simple salts, which is associated with molecular reaction of a longer range order.
