The purpose of the project was to make use of all the information that can be garnered from electron scattering from molecules to obtain detailed information about the structure of molecules. The design and construction of an electron spectrometer was undertaken. Various theoretical studies necessary for the proper interpretation of experimental results were also carried out. Achievements include the calculation of the effect of chemical binding on gas electron diffraction patterns and the experimental observation of this effect in the molecules H2, NH3, CH4 and H2O. New techniques were developed for the solution of the molecular and atomic integrals needed in the calculation of theoretical electron diffraction intensity curves for comparison with experiment. Partial wave elastic scattering factor calculations were carried out for a number of atoms and new least squares and auto correlation techniques were devised for the refined analysis of electron diffraction data in order to obtain precise molecular parameters. In addition the molecular structures of the compound C6C14H2, C6Br6, cycloheptatriene and perylene were carried out to test these newly developed techniques.
