Counterion NMR in Some Polyelectrolyte Systems
NMR quadrupole relaxation rates of 23Na+ were used to study counterionpolyion interactions for both synthetic and biological macromolecules. The non-exponential relaxation and the non-equality of T1 and T2 permitted an analysis in terms of correlation times, quadrupole coupling constants and amount of counterion binding.
