Abstrakt: We show that the dramatic dependence of pressure on the parameters of the inter-molecular potential can be exploited to tune them to their best values. We support the viability of this strategy by a careful study of a fully diffusive Lennard–Jones fluid, showing that Lennard–Jones parameters can be easily optimized to better than a 1% accuracy.
