F-CENTER ELECTRON QUANTIZATION IN ALKALI HALIDE CRYSTALS Background Alkali halides and alkaline earth halides are strongly ionic compounds
Alkali halides and alkaline earth halides are strongly ionic compounds that solidify as crystals. The name for the alkali elements (Li, Na, K, Rb and Cs) comes from the Arabic word alqili (ashes of the salt-wort plant that was once used as a source of sodium and potassium for making glass from sand). The name for the halogen elements (F, Cl, Br, I—and the rare radioactive element astatine) come...
متن کاملCryptates: Macropolycyclic Inclusion Complexes
Macropolycyclic ligands containing appropriate binding sites and cavities of suitable size and shape, may be designed so as to display molecular recognition in the formation of selective inclusion complexes, cryptates, with metal cations, but also with anions and molecules. Macrobicyclic ligands B form highly stable and selective alkali and alkaline-earth cryptates, displaying a pronounced cryp...
متن کاملمروروی بر تهیه و شناسایی ساختار کمپلکسهای تری اتانول امین
Up to date 12 complexes of triethanolamine with alkali, alkaline earth, lanthanide metals and hydrogen have been reponed. The synthesis and structure determination of these compounds is the subject of this review papacr. Moreover, the similarities and the differences of the complexes with respect to the metals and ligand are discussed.
متن کاملGeochemistry of Rare Earth Element in garnet group minerals in some regional metamorphic complexes - Central Iran Micro-Continent (CIMC)
This study focuses on the amount and concentration of trace elements and REEs pattern in garnet crystals which experienced regional metamorphism in the central Iran micro-continent, including the areas of Deh-Salm, Zaman Abad, Mishdowan, and Tanbour. Generally, garnet crystals are isolated from mica schists of greenschist to amphibolite facies. Mineralogical composition of garnets shows almandi...
متن کاملNuclear magnetic resonance studies of supercooled aqueous electrolyte solutions
The dynamic properties of water molecules coordinated to simple ions (alkali and alkali-earth halides) and hydrophobic ions (tetraalkylammonium (TAA) halides) in supercooled solutions have been investigated with KMR. The study of spin-lattice relaxation rates and self-diffusion coefficients as functions of temperature, pressure, Larmor frequency and concentration reveals characteristic features...
