3DMolecular Symmetry operates in two different modes: the Symmetry Elements mode and the Point Groups mode. To toggle between these modes use the Program Mode Buttons in the upper right part of the GUI. The program's database is searchable through the Search Drop Menus located below the Program Mode Buttons. These menus function in two different ways depending on the program’s mode: the user can search the database and list the molecules containing a particular symmetry element or adopt a certain point group. The Program Mode Buttons and the Search Drop Menus are inactive when an animation of a symmetry operation is in progress or paused. ![]() Click the Program Mode Buttons in the upper right part of the GUI to toggle between the Symmetry Elements mode and the Point Groups mode. Toggling between these modes alters the functionality of the Search Drop Menus and the classification of the listed molecules. In addition, the functionality of the Molecule’s Element selection panel also changes. In the Point Groups mode the symmetry elements are displayed as an hierarchical tree-menu classified by their class, while in the Symmetry Elements mode they are displayed as a list. When toggling from Symmetry Elements to Point Groups mode, the search drop menus are set to the to the point group of the selected molecule and the listed molecules are properly filtered. When toggling from Point Groups to Symmetry Elements mode, the search drop menus are set to "Any Element" and all the symmetry elements of the selected molecule are listed Use the Symmetry Elements drop menus to search the molecules that have a particular symmetry element. From the first drop menu (Element Type) the four types of symmetry elements can be selected, that is, axes, planes, improper axes, center of inversion and an “Any Element” item. In the second drop menu the symmetry elements of the type selected in the first drop menu can be selected. Upon making a selection from either drop menu, the molecules having the particular symmetry element are listed in the Molecules selection panel. Use the Point Groups drop menus to search the molecules that adopt a particular point group. In the first drop menu (Point Group Type) all the types of point groups of chemical interest can be selected, as well the “Any Point Group” item. The second drop menu the point groups of the type selected in the first drop menu can be selected. Upon making a selection from either drop menu, the molecules adopting the selected point group are listed in the Molecules selection panel. |
