摘要
Experimental and computer simulation studies of the rotational relaxation of organic solutes in polar organic solvents and electrolyte solutions are used to investigate the role of solute-solvent dielectric friction. These studies are used to explore the boundaries of applicability for continuum based models of the dielectric frictional coupling and to identify the important molecular mechanisms that define these boundaries. These investigations explore the importance of the solute charge distribution. solvent structure, ion pairing, and hydrogen bonding. (C) 1998 Elsevier Science B.V.
