Gabedit is a graphical interface for the FireFly, Gamess-US, Gaussian, Molcas, Molpro, MPQC, NWChem, OpenMopac, ORCA, and Q-Chem computational chemistry packages. It includes a 3D molecule editor and viewer. Most major molecular file formats are supported, and graphics can be exported in many formats.
The Chemical Structures project aims to provide a complete set of 3D molecular structures in CML format. As CML format permits structural data and many properties to be included, each file also contains additional information, like molecular weight, boiling point, melting point, or InChI code. Data can be explored with a CML-aware software, like Jmol, or by using a Web browser.
ePeriodique is a graphical application which displays the periodic table of the elements. It shows basic data for each element, pictures, Bohr models, and lattice structures. It tries to use the EFL way and provide two themes, one for the desktop (default) and one for small displays (small).
