Water caged in buckyballs

Researchers describe how water molecules 'caged' in fullerene spheres are providing a deeper insight into spin isomers - varieties of a molecule that differ in their nuclear spin. The results of this work may one day help enhance the analytical and diagnostic power of nuclear magnetic resonance and magnetic resonance imaging.
