The Radial Distribution Curve Of "Anomalous" Water By X-Ray Diffraction, Jerome Dechelette

Masters Theses

"Amorphous and liquid samples, believed to be "anomalous" water were studied by X-ray diffraction. A diffusion ring, characteristic of liquids and glass was observed at Θ =10.5º. For purposes of comparison an X-ray diffraction pattern was obtained for pure water under nearly identical conditions. By means of a microdensitometer, X-ray intensity curves were prepared from the diffraction patterns and corrected for absorption and polarization. From the Fourier transform of the intensities, we obtained the radial distribution curves. The radial distribution curve for water, obtained in previous work, shows an initial peak at 2.9Å. This peak is due to the nearest …
