The Gnome Chemistry Utils Library provides some widgets and C++ classes related to chemistry.

Available widgets are:

- GtkPeriodic: a periodic table of the elements.
- GtkComboPeriodic: a combo box witha dropdown periodic table widget.
- GtkCrystalViewer: a crystal structure viewer.
- GtkChem3DViewer: a 3D molecular structure viewer. This widget is also available as a Bonobo control.

The C++ classes are grouped in the gcu namespace. A C interface exists to use some of the functionalities offered in these classes; the corresponding documentation is available in the chemistry.h file.
