Hi all,
Is there some precaution or additional term I should take into account
when calculating the free energy of solvation for a charged molecule?
I plan to make the molecule "disappear" whith lambda moving from 0 to 1
and then perform a thermodynamical integration, this seems to work
reasonably well for neutral molecules. Is there any "gotcha" with
charged molecules? Of course, I'm using PME, pbc=xyz and a large enough
simulation box.
Thanks
