the dimerization constants of safranine t have been determined by studying the dependence of its absorption spectra on the temperature in the range 30–70 ◦c at different total concentrations of safranine t (1.03×10−5, 1.44×10−5 and 1.73×10−5 m). the monomer–dimer equilibrium of safranine t has been determined by applying mcr-als method on the absorption spectra. the quantitative analysis of the...

The dielectric functions of InP, IIla.53 Gao.47 As, and 1110.75 Gao.2S Aso.s P 0.5 epitaxial layers have been measured using a polarization-modulation spectroscopic ellipsometer in the 1.5 to 5.3 eV region. The oxide removal procedure has been carefully checked by comparing spectroscopic ellipsometry and x-ray photoelectron spectroscopy measurements. These reference data have been used to inves...

background some herbal anticancer agents have direct interactions with dna. objectives the present study aimed to investigate the interaction of ctdna with rosemary flowers. materials and methods we used uv-vis, fluorescence and circular dichroism (cd) spectroscopic techniques. results the absorption of dna at 260 nm increased on addition of rosemary. herb extract quench the fluorescence of etb...

benzyl chloride and tin powder were used to prepare dibenzyltin dichloride according to a literatureprocedure. in this study, ir spectroscopy, homo-lumo energy gap, nbo analysis, polarizability,some geometrical parameters, natural charge and electrical potential of atoms, global hardness,electronic chemical potential, global electrophilicity index, and molar volume of dibenzyltindichloride were...
