this effect, but it will also increase the interactions with hydrogens
relative to the other interactions in the soft-core state.

0), and the Coulomb and Lennard-Jones potentials are turned on or off
sequentially, then the Coulombic interaction is turned off linearly,
rather than using soft core interactions, which should be less
