Cross-correlated relaxation in NMR of macromolecules in the presence of fast and slow internal dynamics

We present an anal. of correlation and spectral d. functions involved in autorelaxation and cross-correlated relaxation in the magnetic resonance of macromols. Internal dynamics of the macromol. are described in terms of 2 distinct fluctuation processes with different, slow and fast, correlation times. The approach developed in this work takes into account the possible coupling between both fluctuating internal processes. [on SciFinder (R)]
