WebMO Molecule Editor vs Mirage

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

Mirage applications are intended to be used in science classroom (senior high school). To use this application you need to download and print the marker set: http://mirage.ticedu.fr/?p=2324 How to use the app : Card 1 :Find out what this molecule is and write one sentence about the molecule's geometry ? Card 2 to 6 : Try to explain the following molecule's geometry. (hint : use Lewis, electrons pairs, lone pairs...) Card 7 to 11 : answers for cards 2 to 6, showing molecule's geometry, electrons pair and lone pairs. Card 12 : final answer for cards 1, molecule showing molecule's geometry, electrons pair and lone pairs. Once downloaded this one does not require an Internet connection.
