Abstract
Exact analytical expressions for the dielectric and Kerr functions in both relaxation and steady-state regimes are explicitly calculated by solving the Fokker-Planck-Kramers (FPK) equation for the rotational Br ownian motion of a linear rigid rotor in 3D. The response functions th us obtained generalize and extend all the results recently published o n the topic. The particular cases of the Debye-Smoluchowski and Rocard diffusion models are straightforwardly recovered.
