==== Code ==== This sections summarizes the multicomponent version of the common quantum chemistry methods and capabilities implemented in openLOWDIN, as well as of all available input code keywords. * :ref:`Input` * :ref:`CONTROL` * :ref:`Lib` * :ref:`Outputs` * :ref:`Integrals` * :ref:`HF` * :ref:`SCF` * :ref:`Potentials` * :ref:`Properties` * :ref:`DFT` * :ref:`MBPT` * :ref:`PT` * :ref:`CI` * :ref:`NOCI` .. Since Pythagoras, we know that :math:`a^2 + b^2 = c^2`. .. .. .. math:: .. .. (a + b)^2 = a^2 + 2ab + b^2 .. .. (a - b)^2 = a^2 - 2ab + b^2
