Rietveld refinement of incommensurate low tridymite
Zeitschrift für Kristallographie - Crystalline Materials, 2003Abstract The incommensurate modification of SiO2 low-tridymite was refined in the 3 + 1 dimensional superspace group Cc(α0γ) 0 at 295 and 325 K from X-ray powder diffraction data. The displacive modulation mainly consists of tiltings of rigid SiO4/2 tetrahedra with the wave vector r = 0.656a* – 0.496c* (dimensions of the average cell: a =

Restraints and constraints in Rietveld refinement
1993Abstract In the same year as Rietveld’s paper, ‘A Profile Refinement Method for Nuclear and Magnetic Structures’ appeared (Rietveld 1969), Meier and Villiger ( 1969) published an article, the German title of which could be translated as ‘A Distance Refinement Method for the Determination of Atomic Coordinates of Idealized Framework ...
