Research output: Contribution to journalArticlepeer-review


2-mm band EPR spectroscopy was used to compare the spectra of paramagnetic particles produced under adsorption of p-quinones (p-benzoquinone, chloranil, fluoranil) on an activated surface of HY zeolites, p-quinone cation and anion radicals, and the complexes of p-quinones with AlCl3 in a frozen nonpolar solvent. The adsorption is observed to give rise to the paramagnetic complexes of quinones and zeolite surface Lewis sites.
