Solvation and reorganization energies in polarizable molecular and continuum solvents
The solvation free energy difference, DG , and reorganization energy, l, of the electronic transition between the ground and first excited state of formaldehyde are investigated as a function of the solvent electronic polarizability in aqueous solution. Solvent shifts are difficult to measure experimentally for formaldehyde due to oligomer formation; shifts for acetone, which have been measured...
متن کاملEstimation of the solvent reorganization energy and the absolute energy of solvation of charge-transfer states from their emission spectra.
We report herein the solvent and temperature effects on the emission of the intermolecular exciplexes 1-cyanonaphthalene/triethylamine and 1-methylnaphthalene/triethylamine and the intramolecular exciplexes formed by the bichromophoric compounds diethyl-(3-naphthalen-1-yl-propyl)-amine (I), diethyl-(2-naphthalen-1-yl-ethyl)-amine (II), 3-[ethyl-(2-naphthalen-1-yl-ethyl)-amino]-propionitrile (II...
متن کاملSolvation and acid strength effects on catalysis by faujasite zeolites
Kinetic, spectroscopic, and chemical titration data indicate that differences in monomolecular isobutane cracking and dehydrogenation and methanol dehydration turnover rates (per H) among FAU zeolites treated thermally with steam (H-USY) and then chemically with ammonium hexafluorosilicate (CDHUSY) predominantly reflect differences in the size and solvating properties of their supercage voids r...
متن کاملIon solvation in liquid mixtures: effects of solvent reorganization.
Using field-theoretic techniques, we study the solvation of salt ions in liquid mixtures, accounting for the permanent and induced dipole moments, as well as the molecular volume of the species. With no adjustable parameters, we predict solvation energies in both single-component liquids and binary liquid mixtures that are in excellent agreement with experimental data. Our study shows that the ...
متن کاملNew solvation free energy function comprising intermolecular solvation and intramolecular self-solvation terms
Solvation free energy is a fundamental thermodynamic quantity that should be determined to estimate various physicochemical properties of a molecule and the desolvation cost for its binding to macromolecular receptors. Here, we propose a new solvation free energy function through the improvement of the solvent-contact model, and test its applicability in estimating the solvation free energies o...
