Fluorescence polarization measurements of protoporphyrin embedded in the heme-pockets of myoglobin and hemoglobin reveal three different rotational regimes of the porphyrin which are temperature-dependent. At very low temperatures, porphyrin motions in the cavity depend upon the viscosity of the ext
