The following coefficients must be defined for each pair of atoms

:doc:`read_data <read_data>` or :doc:`read_restart <read_restart>`

commands, or by mixing as described below:

For *coul/long* and *coul/msm* no cutoff can be specified for an

individual I,J type pair via the pair\_coeff command.  All type pairs

use the same global Coulombic cutoff specified in the pair\_style

use the same global Coulomb cutoff specified in the pair\_style

command.

These pair styles write their information to :doc:`binary restart files <restart>`, so pair\_style and pair\_coeff commands do not need

to be specified in an input script that reads a restart file.

This pair style can only be used via the *pair* keyword of the

:doc:`run_style respa <run_style>` command.  It does not support the

These pair styles can only be used via the *pair* keyword of the
