Quick description
|
|
-----------------
|
|
|
|
The :ref:`scf` program performs *Restricted* Hartree-Fock
|
|
calculations (the spatial part of the |MOs| is common for alpha and beta
|
|
spinorbitals).
|
|
|
|
.. seealso::
|
|
To see the keywords/options associated to the |SCF| algorithm itself,
|
|
see the documentation of the :ref:`module_scf_utils` module.
|
|
|
|
|
|
More advanced description
|
|
-------------------------
|
|
|
|
The Hartree-Fock algorithm is a |SCF| and therefore is based on the
|
|
:ref:`module_scf_utils` module.
|
|
|
|
The Fock matrix is defined in :file:`fock_matrix_hf.irp.f`.
|
|
|
|
|
|
.. seealso::
|
|
For a more detailed description of the |SCF| structure,
|
|
see the documentation of the :ref:`module_scf_utils` module.
