ELECTRONIC STRUCTURE AND CHEMICAL BOND IN KN3 AND KSCN CRYSTALS

Журнал структурной химии, 2015
Crystal structure parameters, band spectra, distribution maps of the toal and partial electron densities of KN3 and KSCN are calculated from the first principles using the density functional method and the general properties and distinctions in the band spectra are analyzed. The groups of balance subbands are qualitatively similar; in the upper valence

Far infrared spectroscopy of the phase transition in KSCN

Ferroelectrics, 1990
Abstract Polarized reflectivity and transmissivity of KSCN were measured in the spectral range 6–650 cm−1 and temperature region 15–430 K. The absorption at ν < 100 cm−1 for temperatures down to 100-200 K is several times greater than it would follow from t fit of the reflectivity to a sum of classical oscillators.

Computer simulation of diffuse scattering from KSCN crystal

Phase Transitions, 1996
Abstract The diffuse scattering functions for two-dimensional model of KSCN crystal has been studied by the moleculx-dynamics simulation technique. We show that below the tetragonal orthorhombic phase transition the width of the diffuse peak remains temperature independent, although its intensity increases when the temperature approaches Tc from below.

2D 39K NMR study of the phase transition in KSCN

Solid State Communications, 1995
Abstract Two-dimensional (2D) “separation of interactions” 39K 1 2 → −1 2 NMR measurements of KSCN show that the line broadening around and above Tc is purely homogeneous. The disordering process above Tc is thus of dynamic and not of static origin.

Birefringence study of the 415 K phase transition in KSCN

Journal of Physics: Condensed Matter, 1990
KSCN shows an order-disorder phase transition at 415 K. Accurate measurements of the birefringence in the temperature range from room temperature to 420 K support the validity of the Ising model with volume-dependent interactions. The temperature dependence of the birefringence is well correlated with the structural changes as predicted by the ...

ChemInform Abstract: The Electrochemistry of Chromium(III) in Molten KSCN.

Chemischer Informationsdienst, 1986
AbstractThe reduction of Cr3+ in molten KSCN (200°C) is quasi‐reversible, with a formal rate constant of 4‐7·10‐4cm s‐1.

Solution growth of large, high quality KSCN crystals

Journal of Crystal Growth, 1989
Abstract Acetone turned out to be a proper solvent for the growth of large high quality KSCN crystals. A method for the purification of the solution is described together with an experimental set-up for the growth. The habit of the crystals is significantly different for crystals grown out of acetone and out of methanol.

The Induction by Complement of a Change in KSCN-Dissociable Red Cell Membrane Lipids

The Journal of Immunology, 1976
Abstract During complement lysis of antibody-sensitized sheep erythrocytes (EA) there was a larger loss of membrane phospholipids than during lysis elicited by hypotonic buffer. In addition, membranes prepared from complement-lysed EA had a marked reduction in KSCN (2.4 M)-dissociable membrane cholesterol and phospholipids, as compared ...

Dynamic Acoustic Anomalies in KSCN Near the Improper Ferroelastic Phase Transition

Ferroelectrics, 2005
The tensor of the elastic stiffness constants Cij of potassium thiocyanate (KSCN) has been measured in the temperature range 290 K to 420 K, including the order-disorder phase transition at 415 K, by the ultrasonic pulse echo overlap method at frequencies f = 20 MHz.
