^*Residual error function, (Eq. 4), after minimization.

^†Input δ_dip(obs) data set.

^‡Number of protons in each input data set.

^§Euler angles, in degrees, as defined for Eq. 2 and in Fig. 1.

^¶Data set I used all residues with a proton with δ_dip > |0.5|ppm, and was presented previously (30).

^‖Data set II consists of expected rigid protons with significant δ_dip(obs) which are unambiguously assigned at all temperatures; they are identified in the caption to Fig. 6.

^**Magnetic axes and anisotropies reported for sperm whale metMbCN (29).
