21. 14 were considered, but the simplest, which assumes the contribution from the nearest Fe is dominant, is considered adequate in this case.

23. Isotropic shifts for the bis 1-MeIM complex of 1 were found to obey the Curie - Weiss law over the temperature range 233-333 K, consistent with the existence of a single S = 1 spin state for this complex over this temperature range.
