β¦ Synopsis
A simple model of a molecular crystal is used to resolve apparent inconsistencies between existing approaches apphed m calculations
of polarization energies on the one hand and charge-transfer intezgals on the other.

The conlniution to\_btbce dynamics of molecular crystals of polarization interaction due Lo dipoles induced by the molecular multipolar field has been evaluated by calculation of the lattice frequencies of crystalline ammonia\_ It has been found that this contribution is small but not negligible.

The general solution for the effective polarizability in naphthalene-type crystals depends on two arbitrary parameters. These are eliminated by fixing one principal axis of polarizability parallel to a molecuiu -,k; numcricd results are given for naphthalene.
Studies have been made of the electrical polarization resulting from the passage of current in single crystals of low-oxygen thorium oxide at elevated temperatures . The emf . across the crystal necessary to maintain a constant current rises by a factor of 100 and more during the establishment of th
