The effect of temperature on the spin-lattice ( R , ) and spin-spin (R,) I3C relaxation rates of gluconate and manganese (II)-gluconate interactions was determined in D,O. An R, vs T-' minimum was observed for gluconate similar to that observed in solid-liquid phase transitions. Nuclear Overhauser e

The interactions of butanol and mixtures of butanol and ethanol with dipalmitoylphosphatidyl choline (DPPC) liposomes have been investigated by both spectrophotometfic measurements and Fourier transform 13C nuclear magnetic resonance spectroscopy. The spectrophotometric experiments indicate that but
relaxation times (1 Is) of cryptands [2.1.1], [2.2.1] and [2.2.2] as well as those of the corresponding crypeate complexes with Li+, Na+, and K+ in CDCl and CH OH:D 0 (9O:lO) were measured and the results are interpreted in terms of molesular co oreszion % and desolvation effects.
