Occurrence of large temperature-activated dipole moments in sulfur clusters in zeolite inclusions

A lattice of S28 sulfur clusters is obtained in the zeolite cavities NaA. The dielectric constant of the system e' increases with the temperature and reaches a value of ~ 160, which is much larger than that for the original components, and then decreases sharply. It is assumed that the increase of e' is due to thermal excitation in the clusters of the Jahn-Teller states which produce free dipole moments as a result of interaction with the medium.
