Magic angle spinning solid-state NMR of labeled ImmH (upper panel) and DADMe-ImmH (lower panel) to compare bond distortions. Peaks at 108.6 and 104 ppm are the 9-13C in bound and free ImmH. Peaks at 62.9 and 54.0 are the 1′–13C label in bound and free ImmH. Peaks at 103.0 ppm and 102.3 ppm are the 9-13C label in bound and free DADMe-ImmH. Peaks at 47.4 and 45.8 ppm are the 13CH2 in diastereomers of free protonated DADMe-ImmH. Pak at 45.0 ppm corresponds to the 13CH2 label in the sole diastereomer present in PNP-bound protonated DADMe-ImmH. Reproduced with permission from ref 381.
