The rotational re-orientations times of the 7-[diethylamino]-2H-1-benzopyran-2-one (7-DHB) dye mol. have been examined in ethanol and octanol solvents when macroscopic solvent viscosity parameter is varied by varying the temperature, by employing the steady-state fluorescence depolarisation and Time-Correlated Single Photon Counting (TCSPC) techniques. Exptl. observation shows that 7-DHB probe is experiencing higher friction in octanol compared to ethanol and rotates slower by a factor of 7.3. The hydrodynamic Stokes Einstein’s Debye theory (SED) with a stick, slip boundary conditions parameters, quasi-hydrodynamic models (Dote-Kivelson-Schwartz and Geirer-Wirtz) were used to determine mech. friction and found an interesting towards super slip trend. Dielec. frictional theories of point dipole, Nee-Zwanzig and van der Zwan-Hynes both models fail to describe exptl. observe dielec. friction trends. Evidently, both hydrodynamic and dielec. models failed to explain the examined behavior, even in the qual. way in alcs.
