Abstract

Values for the exchange-coupling constant J and the double-exchange parameter B have been estimated for dimeric and hexameric mixed-valence iron clusters. For sulfur-bridged species the range of J values is 300-450 cm^-1, and B values vary between 320 and 400 cm^-1. For an OH-bridged diiron cluster B is as large as 1300 cm^-1.
