The rotational motion of the water molecules in analcime has been investigated by quasielastic incoherent neutron scattering. Reorientational times vary from 65 \_+ 20 ps at 260 K to 26 \_+ 3 ps at 370 K, and the temperature dependence suggests an activation energy for reorientations of 780\_+ 200 K
