Abstract

EPR, ENDOR and TRIPLE resonance spectra were recorded for 1,8‐dihydroxy‐3‐methyl‐9,10‐anthraquinone and 9,10‐anthraquinone‐2‐carboxylic acid anion radicals and the 9,10‐anthraquinol‐2‐carboxylic acid cation radical. EPR spectra were recorded for the 5,8‐dideuterio‐1,4‐dideuterioxy‐9,10‐anthraquinone anion radical, the 6,7‐dideuterio‐1,4‐dideuterioxy‐9,10‐anthraquinone anion radical and the 1,4‐dihydroxy‐9,10‐anthraquinol cation radical. The coupling contants of the 1,4‐dihydroxy‐9,10‐anthraquinone anion radical were assigned by deuteriation.
