Notes:
Spin-lattice relaxation rates of the 13C responses of pyridine were measured in the presence of aqueous sucrose and sodium alginate solutions and calcium alginate gels. In each case the results indicated a reduction in the overall tumbling rate of pyridine compared with that in aqueous media due to molecular association with the carbohydrate. Although anisotropic motion about the C-4:N axis of pyridine was apparent in the sucrose solutions no consistent trends were observed for the alginate samples.
