## Abstract Carbon‐13 dipolar spin‐lattice relaxation times can be used to study microscopic ion mobility in solvent‐separated and contact ion‐pair systems. Two chemically stable ion pairs were studied. Cyclohexylammonium formate observed in a number of solvents allows correlation of relaxation tim

## Abstract The NMR. spectrum of guanidinium ion 1 is studied in anisotropic liquid crystalline nematic solution. Assuming an HNH‐angle of 120°, the distance ratio NH/NC = 0.784 is obtained, from which using NC = 1.330 Å (from X‐ray data) NH = 1.043 Å results. An upper bound for the free energy of
