| - The NMR rotational correlation equations for dipolar relaxationbetween 1H and the nuclei, 1H, 13C,31P, and113Cd have been solved for viscous solutions using theR2/R1 dipolar ratio.The rotational correlation timeshave been determined over the dipolarR2/R1 range of 1.1−1200at field strengths of 4.7, 6.35, 7.05, 9.4,11.75, and 14.1 T. The calculated correlation times at each fieldstrength have been fitted to pairs ofpolynomials which reproduce the correlation times fromR2/R1 values at a giventemperature. The 13C−Hand 1H−1H equations are used to determine the27Al nuclear quadrupole coupling constants in 1:2LiCl−ethylaluminum dichloride melts and neat ethylaluminum dichloride.The 113Cd−1H and31P−1H polynomialsare used to characterize Cd2+ and inorganic phosphatebinding sites in the enzyme, yeast inorganicpyrophosphatase.
