Solution \*sM-ENDOR and TRIPLE n~~~~+nce esperiments have been performed on the bacteriochlorophyll a (BChl a) zJ anion and cation radicals enriched in 25hIg. The 2shfg isotropic hyperfime coupling constants for BChl a\* and BChl ar have been determined. The vaIues are in good agreement with those o

## 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‐
