Characterization of Chemical Exchange Using Residual Dipolar Coupling
Abstract in Undetermined NMR line shape analysis and relaxation dispersion measurements for N,N-dimethyltrichloroacetamide (DMTCA) weakly aligned using poly-γ-benzyl-l-glutamate, which forms a lyotropic nematic phase when dissolved in chloroform, were used to characterize chemical exchange kinetics for the rotation around the C−N amide bond. At low temperatures (<312 K), slow-exchange 1H-coupled 1
