• The rotational viscosity coefficients (RVCs) γ_i (i - 1,2), and ratio of the RVCs λ=γ_2/γ_1, for nematic liquid crystals (NLCs) are investigated by combination of existing statistical-mechanical approaches (SMAs), based on a rotational diffusion model and computer simulation technique. According to the SMAs, γ_i are found to be a function of temperature, density, rotational diffusion coeffcient (RDC), orientational distribution function (ODF) and number of order parameters (OPs). The RDC, OPs and the ODF were obtained from an analysis of a trajectory generated in a molecular dynamics simulation using realistic atom - atom interactions. In addition, set of OPs, and ODFs calculated in the framework of integral equation approach, for the dipolar Gay - Berne model, was used for evaluation of γ_i and λ. Reasonable agreement between calculated and experimental values of γ_i and λ is obtained. Calculations also predicts a flow aligning regime for 5CB nematic phase.
