The Range-separated Kohn-Sham module performs *Restricted* range-separated Hybrid calculation,
which means that only the long-range part of the *exact* exchange is taken into account.

The program associated to it is the :ref: `rs_ks_scf` executable.

such as the exchange/correlation functionals or the range-separation parameter.

The splitting of the interaction between long- and short-range is determined by the range-separation parameter :option: `ao_two_e_erf_ints mu_erf` . The long-range part of the interaction is explicitly treated with exact exchange, and the short-range part of the interaction is treated with appropriate DFT functionals.
The Range-separated Kohn-Sham in an SCF and therefore is based on the :ref: `module_scf_utils` structure.
