Ethane.

Models[edit]

The NERD parameters are:

Molecule \sigma_{\mathrm {CH}_3} \sigma_{\mathrm {CH}_2} \epsilon_{\mathrm {CH}_3} \epsilon_{\mathrm {CH}_2}
ethane 3.825 \mathrm{\AA} 3.93 \mathrm{\AA} 100.6 K

Critical properties[edit]

The pressure, temperature and density at the critical point have been calculated for a virial equation of state using the TraPPE-UA force field, and are given in Table I of [1].

Virial coefficients[edit]

The virial coefficients B_2-B_6 as a function of temperature for the TraPPE-UA force field have been tabulated by Schultz and Kofke [2].

Surface tension[edit]

The surface tension has been calculated for the TraPPE and OPLS force fields [3] using the wandering interface method.

Liquid-vapour equilibria[edit]

The Liquid-vapour equilibria has been calculated for the TraPPE and OPLS force fields [3].
