The NMR relaxation times of the "C(O) nuclei of formanilide, acetanilide, benzamide, benzoic acid, the benzoate anion and glycine were measured for four different magnetic field values, allowing the determination of the contribution of the shielding anisotropy mechanism to the total relaxation rate.
