MOs Module
|
|
==========
|
|
|
|
Molecular orbitals are expressed as
|
|
|
|
.. math::
|
|
|
|
\phi_k({\bf r}) = \sum_i C_{ik} \chi_k({\bf r})
|
|
|
|
where :math:`\chi_k` are *normalized* atomic basis set.
|
|
|
|
The current set of molecular orbitals has a label ``mo_label``.
|
|
When the orbitals are modified, the label should also be updated to keep
|
|
everything consistent.
|
|
|
|
When saving the MOs, the ``mo_basis`` directory of the EZFIO file is copied
|
|
in the ``save`` directory, named by the current ``mo_label``. All this is
|
|
done with the script named ``save_current_mos.sh`` in the ``scripts`` directory.
