Abstract
We discuss the hydrodynamic equations which describe the shear dynamics of a liquid composed of anisotropic molecules, both in its normal and its supe rcooled phases. We use these equations to analyze 90 degrees depolarized li ght scattering experiments performed in the supercooled phase of a glass fo rming liquid, metatoluidine, and show that the information extracted from t his analysis is consistent with independent shear viscosity measurements pe rformed on that liquid in the same temperature range.
