## Abstract The anion radical of 1,2βdiphenylcyclobutene was studied by electron spin resonance. The hyperfine splittings were found to be 0Β·47 and 0Β·74 G for the __meta__βpositions, 2Β·23 and 2Β·69 G for the __ortho__βpositions and 4Β·21 G for the __para__βpositions of the phenyl rings. The methylene
The electron spin resonance spectra of the tris(4-nitrophenyl)methyl and tris(2,3,5,6-tetrafluoro-4-nitro-pheny1)methyl radicals in toluene solution have been obtained and their "N, ' % and 'H hypefine splitting constants have been determined. Analysis of the data indicates that fluorine substituent
