✦ Synopsis

Abstract

Spin‐lattice relaxation rates of the ^13^C 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.
