title: When is a radical not a radical?
abstract: It is not commonly realised that symmetrical Fe(III) complexes are expected to have EPR spectra dominated by a symmetrical narrow line close to the free-spin g-value. The aim of this note is to stress that such features can be mistakenly identified as the spectra for stable organic radicals. This situation is a particular problem in studies of animal or plant tissue samples.
