The combining rules (also known as mixing rules) for binary mixtures are variously given by:

Admur and Mason

For the second virial coefficient of a mixture [1]

Böhm-Ahlrichs

[2]

Diaz Peña-Pando-Renuncio

[3] [4]

Fender-Halsey

The Fender-Halsey combining rule for the Lennard-Jones model is given by [5]

Gilbert-Smith

The Gilbert-Smith rules for the Born-Huggins-Meyer potential[6][7][8].

Good-Hope rule

The Good-Hope rule for MieLennard‐Jones or Buckingham potentials [9] is given by (Eq. 2):

Hudson and McCoubrey

[10]

Kong rules

[11]

Lorentz-Berthelot rules

The Lorentz rule is given by [12]

which is only really valid for the hard sphere model.

The Berthelot rule is given by [13]

These rules are simple and widely used, but are not without their failings [14] [15] [16].

Mason-Rice rule

The Mason-Rice rule for the Exp-6 potential [17].

Sikora rules

The Sikora rules for the Lennard-Jones model [18].

Tang and Toennies

[19]

Waldman-Hagler rules

[20]
