Proton solvation in protic and aprotic solvents

Journal of Computational Chemistry, 2016
Protonation pattern strongly affects the properties of molecular systems. To determine protonation equilibria, proton solvation free energy, which is a central quantity in solution chemistry, needs to be known. In this study, proton affinities (PAs), electrostatic energies of solvation, and pKA values were computed in protic and aprotic solvents.

Photochemistry of 5-aminoquinoline in protic and aprotic solvents

Spectrochimica Acta - Part A: Molecular and Biomolecular Spectroscopy, 2011
Photophysical properties of 5-aminoquinoline (5AQ) have been investigated in various non-polar and polar (protic and aprotic) solvents using steady state and time resolved fluorescence. In aprotic solvents, the spectral maxima depend on the polarity. However, in protic solvents both the fluorescence intensity as well decay time show decrease depending ...

Entering chloride kinetic isotope effects in protic and aprotic solvents

Journal of the American Chemical Society, 1976
Chlorine kinetic isotope effects for the reaction of ethylene oxide and chloride ion are normal (/sup 35/Cl//sup 37/Cl greater than unity) in protic solvents and in acetone and dimethylformamide (DMF) in the presence of 1 equiv of 2,6-lutidinium ion. In the presence of 0.1 equiv of this cation (and 0.9 of Li/sup +/) the isotope effect in DMF is inverse

Rotational diffusion in aprotic and protic solvents

Chemical Physics, 1978
Abstract We present the orientational relaxation times in protic and aprotic solvents for rose bengal in its lowest excited singlet state. The method uses a mode locked dye laser for polarized excitation, and time correlated single photon counting for determination of the time resolved polarized fluorescence.
