**ii. Rotational reorientation times of Exalite 417 (E417)**

The rotational reorientation times of E417 scale linearly with η (Fig. 5) and exhibits subslip behavior in alcohols. A large nonlinearity is observed on increasing solvent viscosity. In alkanes, the rotational reorientation times follow slip hydrodynamic boundary condition, similar to E404. GW theory is unable to explain experimental results while DKS theory is in fairly good agreement with experiment and slip hydrodynamics in case of alkanes.
