This module contains a |CIS| program.
|
|
|
|
The user point of view
|
|
----------------------
|
|
|
|
The :ref:`cis` program performs the CI to obtain the ROHF reference + all
|
|
single excitations on top of it. This program can be very useful to:
|
|
|
|
* **Ground state calculations**: generate a guess for the ground state wave
|
|
function if one is not sure that the :ref:`scf` program gave the lowest |SCF|
|
|
solution. In combination with :ref:`save_natorb` it can produce new |MOs| in
|
|
order to reperform an :ref:`scf` optimization.
|
|
|
|
* **Excited states calculations**: generate guesses for all the
|
|
:option:`determinants n_states` wave functions, that will be used by the
|
|
:ref:`fci` program.
|
|
|
|
|
|
The main keywords/options to be used are:
|
|
|
|
* :option:`determinants n_states`: number of states to consider for the |CIS| calculation
|
|
|
|
* :option:`determinants s2_eig`: force all states to have the desired value of |S^2|
|
|
|
|
* :option:`determinants expected_s2`: desired value of |S^2|
|
|
|
|
|
|
|
|
|
|
The programmer's point of view
|
|
------------------------------
|
|
|
|
This module was built by setting the following rules:
|
|
|
|
* The only generator determinant is the Hartree-Fock (single-reference method)
|
|
* All generated singly excited determinants are included in the wave function (no perturbative
|
|
selection)
|
|
|
|
These rules are set in the ``H_apply.irp.f`` file.
