摘要：

The purpose of this commentary is to stress that in mixed-valence systems, electron localization and electron delocalization are competitive, the first being most often the stronger. In iron-sulfur clusters where a delocalized Fe(II)Fe(III) pair of maximal spin exists, a minimum value of 1200 cm(-1) is proposed or the resonance integral beta parametrizing the electron delocalization.
