A diffusional contribution to lithium isotope effects

Perry Franklin Renshaw

Open full text 12 citations

Abstract

The two lithium isotopes 6Li and 7Li behave differently in biological systems. One possible explanation for these effects is that the isotopes diffuse at slightly different rates due to their different masses. Using nuclear magnetic resonance (NMR) techniques, the aqueous diffusion constants of both 6Li and 7Li were measured. A small difference in these diffusion constants was detected, the magnitude of which is consistent with that predicted theoretically.
