Editing Equation of state (section)

=== Perturbation theory-based models ===
[[Perturbation theory]] is frequently used for modelling dispersive interactions in an equation of state. There is a large number of perturbation theory based equations of state available today,<ref>{{Cite journal|last1=Betancourt-Cárdenas|first1=F.F.| last2=Galicia-Luna|first2=L.A.|last3=Sandler|first3=S.I.|date=March 2008|title=Equation of state for the Lennard–Jones fluid based on the perturbation theory|url=https://linkinghub.elsevier.com/retrieve/pii/S0378381207007030|journal=Fluid Phase Equilibria| language=en|volume=264|issue=1–2|pages=174–183|doi=10.1016/j.fluid.2007.11.015|url-access=subscription}}</ref><ref>{{Cite journal| last1=Levesque|first1=Dominique|last2=Verlet|first2=Loup|date=1969-06-05|title=Perturbation Theory and Equation of State for Fluids | url=https://link.aps.org/doi/10.1103/PhysRev.182.307|journal=Physical Review| language=en|volume=182| issue=1| pages=307–316|doi=10.1103/PhysRev.182.307|bibcode=1969PhRv..182..307L|issn=0031-899X|url-access=subscription}}</ref> e.g. for the classical Lennard-Jones fluid.<ref name="Stephan 112772"/><ref>{{Cite journal |last1=Lenhard |first1=Johannes |last2=Stephan |first2=Simon |last3=Hasse |first3=Hans |date=February 2024 |title=A child of prediction.
