Table 3.1

$ ^\star \! D_i$ Self-diffusivity of component $ i$ in a binary system $ D_i \cong \left( 1 + \frac{\partial \ln \gamma_i}{\partial \ln c_i}
\right)   ^\star \! D_i$ $ C$ -frame or $ V$ -frame
$ ^\star \! D_i$ is the self-diffusivity of component $ i$ in a chemically homogeneous binary system. $ ^\star \! D_i$ is related to $ D_i$ as indicated. $ ^\star \! D_i$ is usually determined using an isotope. Because there is no net mass flow, the $ C$ -frame is also a $ V$ -frame, and either may be used.
