Abstract

"In the development of X-ray scattering intensity curves physical models are necessary for the theoretical mathematical development involved. The purpose of this paper is the development of a physical model suitable for X-ray diffraction analysis or a linear polymer.

X-ray intensity patterns may be used to give a greater insight as to the atomic structure, configuration or atoms, molecular weight, and therefore a greater knowledge of the structure of matter, both microscopic and macroscopic. The converse may sometimes be used. An atom or molecular model is constructed, from this model X-ray scattering curves may be derived. These curves may be compared with known physical curves and if correct give us a greater insight into the mechanics or the interaction of matter.

The success or failure of the model depends on the details involved in constructing the model. The model should have characteristics that represent the outstanding property of the real material. If potential energy is assumed to of prime importance, then the model should be constructed so that potential energy is the predominate parameter in describing the system.

The following model takes the chemical-structure unit of the polymer as a unit or cell, and assumes the displacements of the cells are small enough such that the force between two adjacent structural-units is proportional to their separation distance"--Introduction, page 1.
