Intrinsic viscosity $${\displaystyle \left[\eta \right]}$$ is a measure of a solute's contribution to the viscosity $${\displaystyle \eta }$$ of a solution. It should not be confused with inherent viscosity, which is the ratio of the natural logarithm of the relative viscosity to the mass concentration of the polymer. Intrinsic … See more Generalizing from spheres to spheroids with an axial semiaxis $${\displaystyle a}$$ (i.e., the semiaxis of revolution) and equatorial semiaxes $${\displaystyle b}$$, the intrinsic viscosity can be written See more The intrinsic viscosity is very sensitive to the axial ratio of spheroids, especially of prolate spheroids. For example, the intrinsic viscosity can provide rough estimates of the … See more It is possible to generalize the intrinsic viscosity formula from spheroids to arbitrary ellipsoids with semiaxes $${\displaystyle a}$$ See more The intrinsic viscosity formula may also be generalized to include a frequency dependence.
