A new analytical method for solving complex crystal structures
With the aid of an identity it is shown that relationships between signs of structure factors for centre-symmetrical crystals can be obtained even when the Haxker-Kasper inequality considerations yield no useful information.. It is shown that a structure determination can be formulated as a self-consistency problem wi…
Nuclear Quadrupole Effects and Electronic Structure of Molecules in the Solid State
Measured nuclear quadrupole effects in solids are discussed, compared with nuclear quadrupole coupling in gases, and correlated to some extent with molecular structure in the solid state. The iodine crystal affords a good example of intermolecular interactions in the solid state. In this crystal, nuclear quadrupole ef…

PRINCIPLES OF GLASS-BEAD REFLECTORIZATION
THE CHEMICAL COMPOSITION, PHYSICAL PROPERTIES AND PRINCIPLES OF APPLICATION OF GLASS BEADS ARE REVIEWED. ALL THE PROPERTIES OF GLASS WHICH SIGNIFICANTLY AFFECT BEAD REFLECTORIZATION ARE DIRECTLY RELATED TO COMPOSITION. CHEMICAL DURABILITY AND SERVICEABILITY ARE NOT SYNONYMOUS TERMS IN DEFINING THE QUALITIES OF GLASS B…

The Interlayer Binding in Graphite
The repulsive energy between layers of the graphite crystal has been calculated as an interaction of LCAO molecular orbitals in the layers. The van der Waals attractive term was found by setting the energy minimum to fall at 3.37A. When values of the effective nuclear charge and effective quantum number proposed by Ko…
Irreversible Dehydration in Montmorillonite
In a paper to the Faraday Society (1946), Mering showed that the temperature to which one required to heat montmorillonite to produce irreversible collapse of the c-axis depended on the exchangeable cation. With Na-montmorillonite irreversibility began at about 550°C but with Ca-montmorillonite below 350°C During a st…
The crystal structure of thorium and zirconium dihydrides by X-ray and neutron diffraction
Thorium forms a tetragonal lower hydride of composition ThH{sub 2}. The hydrides ThH{sub 2}, ThD{sub 2} and ZrD{sub 2} have been studied by neutron diffraction in order that hydrogen positions could be determined. The hydrides are isomorphous, and have a deformed fluorite structure. Metal-hydrogen distances in thorium…
