Multiple-detector System for Powder Diffraction Using Synchrotron Radiation
A multiple-detector system for powder diffraction using synchrotron radiation was built and has been operated at the Photon Factory in Tsukuba since May, 1995. The optics design is based on a flat-specimen-reflection geometry using parallel-beam, and the intensity data are collected by using asymmetric 2@stepscanning at a fixed incident angle. The multiple-detector system makes it possible to c...
متن کاملMethylergometrine maleate from synchrotron powder diffraction data
The title compound {systematic name: 9,10-didehydro-N-[1-(hydroxy-meth-yl)prop-yl]-d-lysergamide maleate}, C(20)H(26)N(3)O(2) (+)·C(4)H(3)O(4) (-), contains a large rigid ergolene group. This group consists of an indole plane connected to a six-membered carbon ring adopting an envelope conformation and N-methyl-tetra-hydro-pyridine where the methyl group is in an equatorial position. In the cry...
متن کاملAlaptide from synchrotron powder diffraction data
THE TITLE COMPOUND [SYSTEMATIC NAME: (8S)-8-methyl-6,9-diaza-spiro-[4.5]decane-7,10-dione], C(9)H(14)N(2)O(2), consists of two connected rings, viz. a piperazine-2,5-dione (DKP) ring and a five-membered ring. The DKP ring adopts a slight boat conformation and the bonded methyl group is in an equatorial position. The five-membered ring is in an envelope conformation. In the crystal structure, in...
متن کاملNew synchrotron powder diffraction facility for long-duration experiments
A new synchrotron X-ray powder diffraction instrument has been built and commissioned for long-duration experiments on beamline I11 at Diamond Light Source. The concept is unique, with design features to house multiple experiments running in parallel, in particular with specific stages for sample environments to study slow kinetic systems or processes. The instrument benefits from a high-bright...
متن کاملAbinitio structure determination using dispersive differences from multiple-wavelength synchrotron-radiation powder diffraction data.
The purpose of this paper and a test case study is to assess a method of ab initio structure solution from powder diffraction data using f' difference techniques. A theoretical foundation for the approach used is first provided. Then, with a test case (nickel sulfate hexahydrate), it is shown that both the position of the anomalous scatterer (Ni) can be determined and the structure can be devel...
