| Abstract: | The value and temperature dependence of the Maxwell relaxation time of viscous tensions and the Lagrangian particle radius, which are the main space-time scales in the Lagrange theory of thermal hydrodynamic fluctuations, are discussed. These parameters play the key role in the estimations of the relative value of the collective component of the molecular self-diffusion coefficient. Special attention is paid to the consistency of estimates obtained by different methods. |
