The development of structural models for predicting the external morphology of crystalline materials is presented and discussed in terms of their applications to molecular crystals. The predicted crystal morphologies of a number of molecular materials including alpha -sulphur, naphthalene, benzoic acid and hexamine are presented using the Bravais-Friedel-Donnay-Harker, attachment energy and Ising models. The results of the various models are compared both against each other and against the experimentally observed morphologies.

The temperature dependence of the pure nuclear quadrupole resonance frequencies in three solid phases of para‐dichlorobenzene has been measured in the range of 77° to 300°K and compared with the measurements of Babushkina and Baisa. Good agreement with the Bayer—Kushida theory is obtained.
