Insights into the Mobility of Methyl-Bearing Side Chains in Proteins from <sup>3</sup><i>J</i><sub>CC</sub> and <sup>3</sup><i>J</i><sub>CN</sub> Couplings
Side-chain dynamics in proteins can be characterized by the NMR measurement of (13)C and (2)H relaxation rates. Evaluation of the corresponding spectral densities limits the slo...
