The locations of hydrogen and deuterium atoms and water molecules have been investigated in carbon monoxide myoglobin using neutron diffraction, and the results are compared with earlier work on metmyoglobin. Parallel real space refinements on the two molecules show relatively few changes, but do show the carbon monoxide molecule with the iron atom moving into the heme plane.
