Eqs. 3 and 4 show the electron-nuclear relaxation-rates for the spin-lattice (longitudinal) and spin-spin (transverse) relaxation-rates. In both of these equations, the first terms reflect the dipolar term, and the second part reflects the scalar interaction. The dipolar term contains a distinct r distance term between the electron of the metal atom and the respective carbon atom in contrast, the scalar term has none.

Electron-nuclear relaxation studies with TEMPOL -labelled carbohydrate molecules, e.g. P-D-glucopyranose derivative 1, allowed the evaluation of intramolecular interspin distances up to 10-15 A in length with good accuracy. In a symposium report, hydrogen-bonding in small sugar molecules (threitol, erythritol, -D-glucopyranose, maltose) as described by the 1992 version of MM3, has been compared with diffraction data obtained by construction and... 

Once one is confident that corrections have been made for binary complexes and diamagnetic contributions to l/r, attention can be paid to one final complication, that is, the lifetime ( ) of the hgand in Ae enzyme complex. The relationship between the experimentally obtained paramagnetic relaxation rate l/Tip, the paramagnetic dipolar electron-nuclear relaxation (Ti ) in the enzyme complex, and the lifetime of this complex is described by...
