Abstract
The Kamlet-Taft solvatochromic parameters describing the dipolarity-Polarizability, hydrogen bond donation ability, and hydrogen bond acceptor ability forethane and six flouorinated ethane solvents were measured using sovatochromic probe molecules. The measured ultraviolet electronic transitions of the probe molecules in a given solvent were fit to third order polynomials in solvent density for all isotherms investigated. Values for the Kamlet-Taft parameters were calculated for each of the solvents as a function of the solvent density. Trends in the Kamlet-Taft values were found relating to the degree of fluorination about the ethane molecule for both the dipolarity-polarizability and the hydrogen bond donor ability. None fo the solvents studied displayed a hydrogen bond acceptor ability.Citation
