From chemically generated anion radicals of anti[2.2](1,4)naphthalenophane 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 a

ESR, ENDOR and triple resonance studies of 1,4-dihydro-1,3-diphenyl-(la) and 3-tert-butyl-1,4dihydro-lphenyl-l,2,4benzotriazinyl (2a) and of the corresponding radical cation 3a (2a protonated at N-4) yielded the magnitude and the sign of almost all of the 'H and I4N hyperfine coupling (HFC) constant
## Abstract The anion radical of 1,2‐diphenylcyclobutene was studied by electron spin resonance. The hyperfine splittings were found to be 0·47 and 0·74 G for the __meta__‐positions, 2·23 and 2·69 G for the __ortho__‐positions and 4·21 G for the __para__‐positions of the phenyl rings. The methylene
