Effects of Anharmonicity of Vibration on the Diffraction of Electrons by Free Molecules
TL;DR: In this article, the effect of nonrigidity of free molecules on electron diffraction data has been examined, and it is shown that conventional procedures of analysis of data lead to ambiguous results which are likely to differ from the true equilibrium internuclear distances by the order of 0.01 A. More exact expressions for the intensity of electrons diffracted by vibrating molecules and corresponding experimental radial distribution curves in terms of the parameters characterizing the potential fields of the molecules are presented.

A neutron-diffraction study of liquid acetonitrile
TL;DR: In this paper, the absolute coherent distinct differential cross section was separated into intermolecular and intramolecular contributions, and the variation of molecular structure in passing from the gas phase to the liquid was obtained from this intra-olecular contribution.

Katsumi Kimura,Masaji Kubo +1 more
TL;DR: In this paper, the molecular structures of dimethyl ether and methyl alcohol were determined in gaseous state by means of the sector-microphotometer method in electron diffraction, and structural information was derived from the resolution of radial distribution curves.

Effects of Anharmonicity of Molecular Vibrations on the Diffraction of Electrons. II. Interpretation of Experimental Structural Parameters
Kozo Kuchitsu,L. S. Bartell +1 more
TL;DR: In this article, the effects of anharmonic vibrations on the molecular intensity function M (s) of electron diffraction and on the radial distribution function f(r) were treated more rigorously to meet current needs.

Internal Motion and Molecular Structure Studies by Electron Diffraction
Isabella L. Karle,Jerome Karle +1 more
TL;DR: In this article, the theory for computing radial distribution curves has been extended to permit accurate curves to be obtained from scattering data covering only a restricted range of angle, which obviates the necessity for visual examination of the diffraction photographs.
