Abstract
A metastable Fe(II) low-spin myoglobin complex with H2O at the sixth c oordination place has been produced by X-ray irradiation of metmyoglob in at 80 K. The relaxation into the equilibrium state of deoxymyoglobi n was investigated as a function of temperature. It starts at temperat ures above 140 K and cannot be understood by assuming one well-defined activation energy. The relaxation is, however, well described by assu ming a Gaussian barrier height distribution.
