Figure 7
A neutron |Fo| − |Fc| Fourier map around His97 in myoglobin. Note the fact that the C(∊1)—H(∊1) bond of this imidazole ring has largely been deuterated (blue contours), while the other C—H group of the ring (upper left of the diagram) still has a red (negative) peak corresponding to an undeuterated H atom. |
