X-ray Diffraction in Liquids [PDF]

Nature, 1927
IN order to find experimental support for the theory of X-ray diffraction in liquids put forward some three years ago by C. V. Raman and K. R. Ramanathan (Proc. Indian Association for the Cultivation of Science, vol. 8, p. 127, 1923), extensive studies have been undertaken in the authors' laboratory of the phenomena observed when a pencil of ...

Chemical, isotopic and gas composition of the first-year sea ice in 2013-2015 from the data of cores taken at the BARNEO drifting stations

Лëд и снег, 2019
As a result of the work performed at the BARNEO drifting stations (2013-2015 in the polar region of the Arctic ocean), a comprehensive testing was carried out and new data were obtained on the structure of one-year sea ice, its salinity, the distribution

Crystal structure of 3-bromo-2-hydroxybenzonitrile

Acta Crystallographica Section E: Crystallographic Communications, 2015
The crystal structure of the title compound, C7H4BrNO, has been determined, revealing a partial molecular packing disorder such that a 180° rotation of the molecule about the phenol C—O bond results in disorder of the bromine and nitrile groups.

The Limits of X-ray Diffraction Theory

Crystals, 2023
X-ray diffraction theory allows the interpretation of experiments to build a structural model that fits the collected data. As with any experimental science, the observations are subject to uncertainty through the instrument and user limitations ...
