established dipolar-recoupling technique to measure dipolar couplings between isolated
pairs of spin-1/2 heteronuclei in solid-state nuclear magnetic resonance. REDOR can also
be used to estimate motional order parameters when the bond distance is known, for
example, in the case of directly bound nuclei. However, the relatively fast dipolar dephasing
for strongly coupled spin-1/2 pairs, such as 13 C–1 H, makes the stroboscopic measurement …
