epsilon_k (float) – Energetic parameter in units of Kelvin.
mu (float, optional) – Dipole moment in units of Debye.
q (float, optional) – Quadrupole moment in units of Debye * Angstrom.
kappa_ab (float, optional) – Association volume parameter.
epsilon_k_ab (float, optional) – Association energy parameter in units of Kelvin.
na (float, optional) – Number of association sites of type A.
nb (float, optional) – Number of association sites of type B.
nc (float, optional) – Number of association sites of type C.
viscosity (List[float], optional) – Entropy-scaling parameters for viscosity. Defaults to None.
diffusion (List[float], optional) – Entropy-scaling parameters for diffusion. Defaults to None.
thermal_conductivity (List[float], optional) – Entropy-scaling parameters for thermal_conductivity. Defaults to None.
