A model for specific interactions of manganese-phthalocyanine in protic media
Extinction coefficients (e) changes of manganese phthalocyanine (Mn-Pc) were studied in different organic solvents and related to solvent polarity scales (Kosower's values (Z), Dimroth's values (ET), donor numbers (DN) and linear solvation energy ...

Solvatochromism of isatin based Schiff bases: An LSER and LFER study [PDF]
The derivatives of isatin have already been reported to show a variety of biological activities. However, there has been no report on solvatochromic effect of isatin derivatives so far, and that could be of interest to study and relate to their ...

Thermal stabilities of DNA duplexes containing Gua (g), α- (a) or β-anomer of formamidopyrimidine-N7-9-hydroxy-aflatoxin B1 (b) differ markedly (Tm: a < g < b ), but the underlying molecular origin of this experimentally observed ...

Equilibrium constants and protonation site for N-methylbenzenesulfonamides
The protonation equilibria of four substituted N-methylbenzenesulfonamides, X-MBS: X = 4-MeO (3a), 4-Me (3b), 4-Cl (3c) and 4-NO2 (3d), in aqueous sulfuric acid were studied at 25 °C by UV–vis spectroscopy.

Determining the orientation of protegrin-1 in DLPC bilayers using an implicit solvent-membrane model. [PDF]
Continuum models that describe the effects of solvent and biological membrane molecules on the structure and behavior of antimicrobial peptides, holds a promise to improve our understanding of the mechanisms of antimicrobial action of these peptides.

Linear free energy relationships in halogen bonds [PDF]
Four models of halogen bonds were used to quantify this bond using the DFT B97D/6-311+G(d) computational level: para-substituted iodobenzenes, para- and meta-substituted bromobenzenes complexed with three simple Lewis bases (NH 3, NCH and CNH), 1-bromo-4-substituted-bicyclo[2.2.2]octanes with NH3 and 3- and 4-substituted pyridines complexed with BrCl ...

Linear Free Energy Relationships in Glass Corrosion [PDF]
AbstractVarious theoretical models that have been proposed to correlate glass durability to their composition for a wide variety of silicate, borosilicate, and aluminosilicate glasses are examined. Comparisons are made between the predictions of these models and those of an empirical formulation extracted from existing data in the present work.
