O CO Some Aspects of Neutron Single Crystal Analysis
نویسنده
چکیده
Introduction This paper presents a few observations on single-crystal analyst*,. based upon experience with the method at the Brookhaven National Laboratory reactor during part of the summer of 1952, and a comparison of neutron and X-ray scattering.. The writer is deeply indebted to Dr. Andrew McE^yrioid and ^is group at the Brookhaven National Laboratory for furnisning the complete facilities with which the KH2PO4 analyst? was possible, and continual aid during the investigation. Discussions witi^ Drs. McReynold, L„ Corliss, J° Hastings and R. Weiss were extremely helpful, as was correspondence with Drs. II. Le</y and S. Wo Peterson of the Oak Ridge National Laboratory.

Accurate molecular structures and hydrogen bonding in two polymorphs of ortho-acetamidobenzamide by single-crystal neutron diffraction.
The structures of both known forms of the polymorphic material ortho-acetamidobenzamide, C(9)H(10)N(2)O(2), have been determined by low-temperature neutron single-crystal diffraction. Neutron diffraction allows the full description of the H-atom positions in this molecular material, which is vital in benchmarking related crystal-structure predictions. Significant conformational differences are ...

The crystal structure of (Li0.5K0.5)2C03 was determined by neutron powder diffraction. A final weighted R-factor of 4.54% was obtained for the refinement of 2373 reflections by the Rietveld method from a sample synthesized using 7Li2CO3 and K2CO3 (99.9% pure). Slight distortion of the CO$units in the monoclinic cell was observed; the O( 1)-C-0(2) angle and CO(3) length are larger than those for...
