✦ Synopsis

Abstract

Hyperfine coupling constants and g‐factors determined by ESR and ENDOR spectroscopy are given for the radical anions of 21 syn‐1,6:8,13‐bridged [14]annulenes. The great majority of these values is reported for the first time. The hyperfine data are consistent with the single occupancy of an orbital which resembles a π‐perimeter‐LUMO of the same nodal properties. The sum of the coupling constants of the protons attached to the π‐perimeter can be used as a planarity criterion for this perimeter.
