## Abstract The EPR spectrum of alimemazine cation radicals (ALMZ^+^) in a perchlorate single crystal has been studied at 293 K. Since strong exchange interactions between the radicals did not allow the determination of the hyperfine splitting constants, the spectrum of an ALMZ^+^ solution, frozen
Radical cations of a series of a-methyl-substituted bi-, ter-and quaterthiophenes were investigated by EPR and, in part, ENDOR spectroscopy. In the case of terthiophenes, the electronic and steric effects of methyl substituents were studied. The experimentally determined spin density distributions w
