What about taking another alkali ion (are thery any in CROMOS53?) and adjusting sigmaepsilon to reflect smaller size of Li(+)? Of course, lithium is a pretty polarizable guy with certain covalent bonding ambitions, but this does not prevent people to simulate it as a hard [+1e] sphere... Dr.

[gmx-users] Lithium Ions in Gromos53A6

2014-10-06 Thread Hardy, Adam
Dear All, I find myself requiring lithium ions in a simulation using (a variant of) the Gromos53A6 forcefield. Chaging forcefields is not an appealing proposition due to the time already invested in the current one, so I was wondering had any suggestions or has perhaps gone to the effort of
