Methane (CH4) is the first in the homologous series of alkanes.
Lennard-Jones parameters
Methane is sometimes simulated as a single Lennard-Jones site using a united-atom model. Some Lennard-Jones parameters for methane are listed in the following table:
| Force-field | (K) | (nm) | Reference |
| OPLS | 147.9 | 0.373 | [1] |
| TraPPE | 148 | 0.373 | [2] |
Three-body model
A Hauschild and Prausnitz [3] like three-body potential has been developed by Abbaspour [4], building on the OPLS model.
Plastic crystal phase
The methane has a plastic crystal phase.
