Abstract: In this work, several polycyclic aromatic radical cations have been studied for the first time by EPR and ENDOR methods.Among these are the radical cations of 1,4,5,8-tetramethylanthracene;9,10-dideuterio-1,4,5,8-tetramethylanthracene;2,6,9,10-tetramethylanthracene;2,6-dimethyl-9, 10-di(p-methylbenzyl) anthracene;3,6,11,14-tetramethyl dibenzo(a,c)triphenylenes.

Key words: EPR, ENDOR, Friedel-Crafts reaction, Radical cation
