dc.description.abstractMossbauer parameters at 125K for both the oxidized and semi-reduced states of FeMoco isolated from the MoFe protein of nitrogenase of [delta]/Fe=0.32 and 0.37 mm/s and [Delta]Eq=0.84 and 0.71 mm/s, respectively, are reported. FeMoco(ox) fits the Debye model perfectly from 4.2-125K and has a S=0 ground state. FeMoco(ox) apparently contains 10-20% FeMoco(s-r) and , possibly as a result of the spontaneous oxidation phenomenon. Quantitation of the spectra indicates a Fe:Mo ratio of 5+/-1:1 and the similar quadrupole splittings and isomer shifts suggest a similar environment for all iron atoms.en_US
