“…Specific solute-solvent interactions were subdivided into solvent Lewis-basicity interactions (hydrogen bond donor (HBD) solute/ /(hydrogen bond acceptor (HBA) solvents) and solvent Lewis acidity interactions (hydrogen bond acceptor (HBA) solute/(hydrogen bond donor (HBD) solvents). Thus, the following multiparameter equation was suggested for application in linear solvation energy relationships (LSER): [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44] LSER have been used in various fields, such as, ionic liquids, solubility, thermochemistry, NMR chemical shifts, pharmaceuticals, etc. Equation (10) has been used in the correlation analysis by multiple regression of numerous reaction rates and equilibria, spectroscopic data and various other solvent dependent processes.…”

The complexation of molybdenum(VI) with methyliminodiacetic acid (MIDA) at pH 6.00, T = 298 K, I = 0.1 mol dm-3 of sodium chloride and different water + methanol solutions (0-45 vol. %) was studied using potentiometric and UV spectrophotometric measurements. The values of the stability constants were calculated and their trends interpreted using the Kamlet-Abboud-Taft (KAT) model in order to investigate the role of different specific and non-specific interactions in aqueous solutions of methanol.

Protic and aprotic solvent effects on the reactivity of picolinic, nicotinic and isonicotinic acid, as well as of some substituted nicotinic acids with diazodiphenylmethane (DDM) were investigated. In order to explain the kinetic results through solvent effects, the second-order rate constants for the reaction of the examined acids with DDM were correlated using the Kamlet-Taft solvatochromic equation. The correlations of the kinetic data were carried out by means of the multiple linear regression analysis and the solvent effects on the reaction rates were analyzed in terms of the contributions of the initial and the transition state. The signs of the equation coefficients support the already known reaction mechanism. The solvatation models for all the investigated acids are suggested and related to their specific structure
