The correlation function for the angular velocity of a Brownian particle suspended in a liquid is analyzed with an account of the viscous aftereffect. The main term in the asymptotic exression for this function is equal to the eddy correlation function for the translational velocity of a liquid ...

Research carried out at the University of Pennsylvania has definitively measured and described the Brownian motion of an isolated ellipsoidal particle, completing a path laid out by Einstein 100 years ago when he first described rotational Brownian motion for spheres in water. Brownian motion, the tin...

Spectral theory of molecular rotation‐induced broadening of hyper‐Raman lines in liquids The spectral line shape of hyper-Raman light scattering in liquids is calculated by the method of irreducible spherical tensors and the theory of rotational Brownian motion. The line broadening due to rotational...
Rotational Brownian Motion and Nonlinear Dielectric Relaxation of Asymmetric Top Molecules in Strong Electric Fields: The Langevin Equation Approach fields. The linear theory of electric polarization of dielectric fluids was formulated originally by Debye [11], who calculated the linear dielectric respo.....

Next, we consider the results of rotational diffusion theory within the framework of relaxation theory, in order to predict relaxation rates measured through NMR spectroscopy. These models may be fitted to experimentally measured NMR relaxation data in order to determine the diffusive hydrodynamic propert...
The stochastic equations of motion are solved for transient and equilibrium averages of the relevant dynamical variables. The single particle rototranslational Langevin equations correspond to the first equation of the Markov chain and (with a rotational constraint) are solved using Wiener matrix algebra...
