WebMO Molecule Editor vs Molecules that changed the World

WebMO allows users to build and view molecules in 3-D, visualize orbitals and symmetry elements, lookup chemical information and properties from external databases, and access state-of-the-art computational chemistry programs. WebMO is recommended for students and faculty in high school, college, and graduate school who desire mobile access to molecular structures, information, and calculations. WebMO capabilities include: - Build molecules by drawing atoms and bonds in a 3-D molecular editor, or by speaking the name (e.g., “aspirin”) - Optimize structures using VSEPR theory or molecular mechanics - View Huckel molecular orbitals, electron density, and electrostatic potential - View molecular vibrations - View point group and symmetry elements of molecules - Lookup basic molecular information, including IUPAC and common names, stoichiometry, molar mass - Lookup chemical data from PubChem and ChemSpider - Lookup experimental and predicted molecular properties from external databases (NIST, Sigma-Aldrich) - Lookup IR, UV-VIS, NMR, and mass spectra from external databases (NIST, SDBS) - Capture high-resolution molecular images - Save and recall molecular structures locally - Export and import structures via email WebMO is also a front-end to WebMO servers (version 14 and higher): - Supports Gaussian, GAMESS, Molpro, MOPAC, NWChem, ORCA, PQS, PSI, Quantum Espresso, VASP, Q-Chem, and Tinker computational chemistry programs - Submit, monitor, and view calculations - View formatted tabular data extracted from output files, as well as raw output - Visualize geometry, partial charges, dipole moment, normal vibrational modes, molecular orbitals, and NMR/IR/UV-VIS spectra

The "Molecules that changed the World" App is meant to convey the scientific facts and interesting stories of molecules that changed our culture, course of civilisation and in short, the world. Among the represented molecules are such basic compounds like water, carbon dioxide, ammonia, which not only influenced the way we think about resources, climate and food production but also affected the development of early life on Earth, and synthetic complex compounds such as nitroglycerin, polyethylene and aspirin. App is aiming at telling you more about the chemical background of such molecules and their influence onto the historical and cultural developments and the life as we know it. This app is a translation of the interactive 3D installation "Molecules that Changed the World" by Ljiljana Fruk and Bernd Lintermann, which was designed at ZKM/Institute for Visual Media to accompany the "Molecular Aesthetics" Symposium held at ZKM | Centre for Art and Media, Karlsruhe, Germany in 2011.
