### Diffusivities calculation (universal)

Universal model for accurate calculation of binary diffusivities of solutes inﬁnitely diluted in gas, liquid and supercritical solvents. Based on a Lennard-Jones model, and contains two parameters: molecular diameter of the solvent and a diffusion activation energy. The model is universal since it is applicable to polar, weakly polar, and non-polar solutes and/or solvents, over wide ranges of temperature and density.
