Stacks: Molecule, Fragment types, Fragments

All levels that are shown are organized in 'stacks': all levels from a molecule or fragment are shown in one (vertical) stack. You may have several stacks visible: one or more molecule, fragment types or fragments.

A molecule stack shows the energy levels of a molecule. These levels correspond one-to-one to molecular orbitals, and using pop-up menus (click and hold) you may instruct ADFlevels to show a particular molecular orbital.

A fragment stack shows the energy levels for a particular fragment. If you have more then one of these fragments in your molecule you may see several of these stacks. The stacks will be identical, but with different interaction lines to the molecular levels.

A fragment type stack shows the energy levels for a particular fragment type. Your molecule may contain one or more fragments of this type. Often it is convenient to collapse individual fragment information into fragment type information: it greatly reduces the clutter.

You control which stacks are visible using menu commands or pop-up menus.
