normal Lennard-Jones parameters. In other force fields, such as
OPLSĀ \ :ref:`103 <refJorgensen88>`, the standard Lennard-Jones
parameters are reduced by a factor of two, but in that case also the
-dispersion (r:math:`^{-6}`) and the Coulomb interaction are scaled.
+dispersion (r\ :math:`^{-6}`) and the Coulomb interaction are scaled.
|Gromacs| can use either of these methods.
