✦ Synopsis

The hyperfine coupling constants and g factor of the mono-, di-and 2,4,6_trimethylbenzoate radical anions are analvzed in terms of a ulanar conformation (in contrast to ortho-substituted benzoic acids).

Theoretical studies support this conclusion.

## Abstract The anion radical of 1,2‐diphenylcyclobutene was studied by electron spin resonance. The hyperfine splittings were found to be 0Β·47 and 0Β·74 G for the __meta__‐positions, 2Β·23 and 2Β·69 G for the __ortho__‐positions and 4Β·21 G for the __para__‐positions of the phenyl rings.
