Relative relaxation-efficiency between two

From these studies of sugars and related molecules, it is possible to derive empirical rules whereby Ri(ns) values can be used as the basis for configurational assignments. These rules are illustrated graphically in Fig. 5, where the relative relaxation-efficiency between two protons is plotted as a function of the interproton distance.
