TraPPE force field

The set of Transferable Potentials for Phase Equilibria (TraPPE) force-field was developed for the simulation of linear and branched alkanes, alcohols, ethers, ketones, and aldehydes. It is based upon the previous OPLS force field.

TraPPE-UA

This is the united atom version of TraPPE

TraPPE–EH

TraPPE publications 3 and 9 provide data for explicit hydrogen simulations.

Parameters
