`cis <http://github.com/LCPQ/quantum_package/tree/master/src/CIS/super_ci.irp.f#L1>`_
  Undocumented


`h_apply_cis <http://github.com/LCPQ/quantum_package/tree/master/src/CIS/H_apply.irp.f_shell_8#L406>`_
  Calls H_apply on the HF determinant and selects all connected single and double
  excitations (of the same symmetry). Auto-generated by the ``generate_h_apply`` script.


`h_apply_cis_diexc <http://github.com/LCPQ/quantum_package/tree/master/src/CIS/H_apply.irp.f_shell_8#L1>`_
  Generate all double excitations of key_in using the bit masks of holes and
  particles.
  Assume N_int is already provided.


`h_apply_cis_monoexc <http://github.com/LCPQ/quantum_package/tree/master/src/CIS/H_apply.irp.f_shell_8#L263>`_
  Generate all single excitations of key_in using the bit masks of holes and
  particles.
  Assume N_int is already provided.


`super_ci <http://github.com/LCPQ/quantum_package/tree/master/src/CIS/super_ci.irp.f#L9>`_
  Undocumented
