On the application of the method of interval normalization to neutron diffraction data from molecular liquids

摘要

A new method of normalization applied to thermal neutron diffraction data on molecular liquids, called interval normalization, is proposed. The method consists of fitting the scattering by the free molecules to the corrected intensity distribution within a limited interval of wave number transfer. The method has been applied to the tetrachlorides of carbon, silicon, titanium, and tin in the liquid state at room temperature. Besides the pursued normalization, the intramolecular interatomic distances and mean amplitudes of vibration are obtained. These intramolecular parameters follow without applying Fourier transform techniques.
