A semi-empirical method of absorption correction
TLDR
An extension of Furnas's method is described in this paper, where the variation of intensity of an axial reflection as the crystal is rotated about the goniometer axis is used to give a curve of relative transmission T against azimuthal angle ϕ for the corresponding reciprocal lattice level.Abstract:
An extension of Furnas's method is described. The variation of intensity of an axial reflection as the crystal is rotated about the goniometer axis is used to give a curve of relative transmission T against azimuthal angle ϕ for the corresponding reciprocal lattice level. Transmission coefficients for any general reflexion hkl are then given approximately by T(hkl) = [T(ϕinc) + T(ϕret)]/2 where ϕinc and ϕret are the azimuthal angles of the incident and reflected beams. Equations are derived for (ϕinc and ϕret and the accuracy of the method is discussed.read more

Synthesis, structure, and characterization of new Li+-d0-lone-pair-oxides: noncentrosymmetric polar Li6(Mo2O5)3(SeO3)6 and centrosymmetric Li2(MO3)(TeO3) (M = Mo6+ or W6+)
TL;DR: Frequency-dependent polarization measurements confirm that Li(6)(Mo(2)O(5))(3)(SeO(3))(6) is nonferroelectric, i.e., the macroscopic polarization is not reversible, or 'switchable'.

Structural features in Tutton’s salts K2[M2+(H2O)6](SO4)2, with M2+ = Mg, Fe, Co, Ni, Cu, and Zn
TL;DR: In this article, the effects of the chemical variation of M 2+ on the structural environment surrounding K, M, and S sites were investigated by single-crystal structure analysis, and the results indicated that the distortion in the SO4 tetrahedron and the M O6 octahedron is very small, except for CuO6 where it is pronounced because of Jahn-Teller effect.
