✦ Synopsis


From chemically generated anion radicals of anti2.2naphthalenophane and 1,4_dimethylnaphthalene, hyperfine coupling constants including relative signs are determined by ENDOR and TRIPLE resonance. The data are compared with spm density distributions obtained by MO calculations. The results are discussed with respect to the spin density distribution in the "special pair" primary donor of bacterial photosynthesis.
