Solute-Solvent interactions in solutions so far are not completely understood. Rotational diffusion studies of medium-sized solute molecules in solvents provide a useful tool to understand these interactions. Due to continuous interactions between solute and solvent with the neighboring particles solute in solvents experiences frictions. By modeling this friction using various continuum theories such as Hydrodynamic, Quasi-Hydrodynamic, and Dielectric friction one gets a better insight into the type of solute-solvent interactions. Rotational dynamics of three mediumly sized laser dyes in a...
