A statistical model is developed in order to discuss orientational disorder introduced during the process of crystal growth. Particular application is made to bromoform crystals. Each molecule is represented by an appropriate distribution of atomic point-charges, and allowance is made for the resulting Coulomb interactions between pairs of molecules, as well as for the dispersion and repulsion forces. The stage-by-stage building up of a crystal is discussed in terms of two statistical parameters: one of these refers to long-range order, the other to short-range order. Molecular orientations are determined by a random-number procedure related to these parameters and to the temperature; and the total energies of interaction are computed between a central molecule and the other molecules of an array of variable size and shape. Several conclusions are drawn regarding the correlation in directions of adjacent molecules. This is very different according to whether the molecules are in the same $ab$ crystal plane (small correlation), or in adjacent planes (high correlation).
