Heteronuclear double‐resonance NMR offers novel insight into fast correlated chemical exchange in biomolecules. The method presented by S. Ulzega et al. on p. 333 allows determining the kinetics of correlated dynamic processes. This approach is supported by an analytical treatment of the contribution of correlated chemical exchange to relaxation (top of the picture), numerical simulations, and experimental results obtained on a mobile residue (Phe45) of human ubiquitin (bottom).
