Check the original specifications for each of those force fields, then
check to see if the molecule you are wanting to simulate falls within
the boundaries of how the force field was derived. Also search the
literature for simulations of the same or similar molecules, and see
which force fields they used.

Subject: [gmx-users] United atom forcefield for long alkane ?
I was planning to simulate a system of long-chain alkane carboxylate
in water with a chemical formula CH3-(CH2)_20-COOH .
For that I was thinking of using an united atom force-field. I found ,
in gromacs, there are two United atom force-field available: GROMOS-96
and OPLS-UA. I was wondering whether some one can suggest which united
atom force-field will be good choice for such a long chain alkane chain
