Abstract
Values for the exchange-coupling constant J and the double-exchange pa rameter 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-b ridged diiron cluster B is as large as 1300 cm(-1).
