[Relaxation par corrélation croisée en RMN de macromolécules en présence de dynamiques internes lente et rapide]
Dans cet article, nous présentons une analyse des fonctions de corrélation et de densité spectrale impliquées dans l'auto-relaxation et la relaxation par corrélation croisée en résonance magnétique des macromolécules. La dynamique interne d'une macromolécule est décrite par deux processus distincts de fluctuations internes respectivement lent et rapide, associés à des temps de corrélation différents. L'approche développée dans ce travail prend en compte un possible couplage entre ces deux types de mouvements internes.
In this paper we present an analysis of correlation and spectral density functions involved in autorelaxation and cross-correlated relaxation in the magnetic resonance of macromolecules. Internal dynamics of the macromolecule are described in terms of two 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.
