Crystalz vs WebMO Premium

Atoms connect in many different ways, a concept that can be difficult to understand without being able to really see what’s going on! Learning and understanding how crystal structures form is precisely one of those topics. Designed by professional educators, Crystalz is the world’s premiere crystal lattice visualization app. Using high definition, three-dimensional models, Crystalz allows the user to view and manipulate all 14 Bravais lattice structures. A perfect textbook companion, this app allows the user to rotate and view the shapes of crystals from any viewpoint as well as see information about cell sizes and angles. Additionally, for the three cubic lattice structures, Crystalz includes two extra viewing modes: a space filling mode that shows the atoms without a wire frame, and a unit cell mode that shows only the portions of the atoms designated to each unit cell. If you’re a chemistry student or just interested in how crystal structures work, then Crystalz is for you!

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
