Spin-isomer conversion of water at room temperature, and quantum-rotor-induced nuclear polarization, in the water-endofullerene H${}_2$O@C${}_{60}$

Benno Meier, Karel Kouřil, Christian Bengs +6

Water exists in two forms, para and ortho, that have nuclear spin states with different symmetries. Here we report the conversion of fullerene-encapsulated para-water to ortho-wate…
