We study de nonlinear optical properties of three ionic liquids of family [BMIM]. The ionic liquids are 1-buthyl-3-methylimidazolium tetrafluoroborate, 1-buthyl-3-methylimidazolium trifluoroacetate, and 1-buthyl-3-methylimidazolium Bis((trifluoromethyl)sulfonyl)imide. We calculate the static molecular polarizability (α) and hyperpolarizability (β,γ) using PM3 model and determinate experimentally the...
Structural parameters and physical properties are tabulated for >100 presently known simple and binary acentric chloride crystals. Distribution of the crystals over point symmetry groups has been defined in comparison with that of fluorides. A rosette of ellipses of acentricity has been outlined on the plane of the shortest chemical bond lengths metal-chlorine in the crystal lattice. A combination...
We study de nonlinear optical properties of organic materials. Multiple rings appear as a CW Ar laser passes through a nonlinear organic liquid. The rings formation is due to spatial self-phase modulation and is observed with 50 mW of continuous wave of Ar laser. We show the dependence between power and rings formed. As a first approximation to value the nonlinear refractive index we use the number...
Structural parameters and physical properties are considered for >100 presently known simple and binary acentric telluride crystals. Distribution of the crystals over point symmetry groups has been defined in comparison with that of selenides. A rosette of ellipses of acentricity has been outlined on the plane of the shortest chemical bond lengths metal-tellurium in the crystal lattice. A set of...
