Lecithin-non-polar solvent-water systems are studied by proton NMR spin-lattice (T~) and spin-spin relaxation (T2) times. T~ studies indicate that one water molecule is tightly bound to the polar head group. The rotational correlation time (re) of the water pool is shortened as a function of added w
## Abstract Highly specific proton lineโbroadening and paramagnetic ^13^C shifts observed for NโbutylโN(4โmethyloxazolโ2โyl)โ2โmethylpropionamide in the presence of fluorinated lanthanide shift reagents, are absent when nonโfluorinated reagents are used. This unusual behaviour is rationalized in te
