On the other hand, the coordination compounds in solution represent a highly dynamic system, since even small differences in the polarity of the solution system may result in an effect on the coordination behavior and, thus, on the catalytic efficiency. Polym. J., Vol. 35, No. 2, 2003 ...
Phyllobilins are now a consistent group of new compounds, with more than 40 different structures completely identified, including a deep knowledge of their chemistry: isomerism, UV–Vis spectrum, polarity, etc. In rough outlines, the biochemistry and the molecular nature of the enzymes implied in...
Infrared spectroscopyFourier transformationReprintsThe infrared linear dichroism of several dozen symmetrical organic molecules of low polarity has been measured on their solid solutions in stretched polyethylene and stretched perdeuterated polyethylene. Both saturated and unsaturated molecules, ranging in size ...
Let Λ be a nonsingular symplectic polarity in (2n-1)-dimensional projective space PG(2n-1,q) over the field GF(q) of q elements. Let PSp 2n (q) be the corresponding projective symplectic group. Suppose that... RH Dye - 《Journal of Algebra》 被引量: 41发表: 1989年 On ...
(490–580 nm). Particle sizes in reaction mixture are larger for P7 and P10 than in water, but smaller for P1. The effect of liquid environment on particle size can be correlated with the relative polarity of the materials: the more polar, sulfone-based polymers disperse better in water...
In pharmaceutical science the partitioning of medicinal agents between immiscible octan-1-ol and water is a common measure of overall polarity. (There is a JAVA partition calculator here.) Turbulent mixing by "shaking the sep' funnel" will maximise the phase boundary surface area and will speed ...
The steady-state absorption and fluorescence spectra, fluorescence quantum yield, and lifetimes in solvents of different polarity at room temperature revealed specific redistribution of the electronic density and rearrangements in molecular geometry after electronic excitation influenced by the dimethylamino end...

The impact of counterion hardness, solvent polarity, and chain length on the geometry, electronic structure, and static third-order polarizability 〈γ〉 of cyanine–counterion pairs [(CH3)2N-(CH)n-N(CH3)2···X] (n=5, 9; X =Cl, Br, I, BF4, ClO4, and PF6) were analysed. A ...
As the solvent polarity increases, the β value increases monotonically. The electronic absorption bands of 1 have been assigned by time dependent density functional theory (TD-DFT).doi:10.1016/j.molstruc.2011.02.044Manoj TrivediR. Nagarajan
