WebMO Molecule Editor vs Vernier Instrumental Analysis

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

Our free Vernier Instrumental Analysis™ app makes it easy to incorporate instrumentation into your chemistry curriculum. The user-friendly interface walks students through the data-collection process and includes instrument-specific analysis features. Collect, analyze, and share data from our Mini GC™, Mini GC Plus, Go Direct® Mini GC, Go Direct Polarimeter, and Go Direct Cyclic Voltammetry System with this free app. Students can collect a gas chromatogram from the Vernier Mini GC, Mini GC Plus, and Go Direct Mini GC. They can also determine peak area and integrate peaks. Using Go Direct Polarimeter, students can collect polarimetry scans and optical rotation data for individual samples, as well as over time. The mutarotation kinetics of sucrose has never been easier to observe. If students have the Go Direct Cyclic Voltammetry System connected, they can easily collect voltammograms to analyze current peaks and determine standard potentials of electrochemical reactions.
