ODYSSEY Chemical Elements против WebMO Premium Использование & Stats

The periodic table of the elements provides the most important organizing principle in all of chemistry. At the molecular level, how similar or how different are the alkali metals? What about the halogens or the first row of the transition metals? Examining and comparing molecular models helps with recognizing patterns and retaining information. ODYSSEY Chemical Elements is a support tool that provides a comprehensive set of models. The app includes accurate models for the standard state of almost all elements in the periodic table. Multiple allotropes are available for all common textbook cases. Using simple gestures, the models can be inspected at any orientation and zoom level and examined using different visualization styles. Where applicable, different isotopes can be detected for the different atoms of a given sample. Many models can also be animated in room temperature simulations, highlighting the distinct differences between solids, liquids, and gases. A glossary, comments section, and set of multiple choice questions (with randomized options) complete the app. Learning about atoms, isotopes, and structural similarities between the elements is an important part of the introductory chemistry curriculum. ODYSSEY Chemical Elements aids this learning with hands-on visual evidence.

WebMO Premium

WebMO Premium is equivalent in functionality to the free 'WebMO' app in conjunction with the 'WebMO Premium' in-app purchase. This paid version is provided for convienence for volume purchases. 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
