WebMO Molecule Editor vs MolSketchGo

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

MolSketchGo is a mobile tool for drawing and exploring chemical structures—for study and personal use. It is not intended for professional, safety-critical, or regulatory decisions. DRAW STRUCTURES • Tap to place atoms; drag between atoms to create bonds • Single, double, triple, wedge, and dash bonds • Long-press to move atoms; use two fingers to pan and zoom • Ring templates: benzene, cyclohexane, and cyclopentane • Skeletal mode, implicit hydrogens, and valence warnings when bonds exceed typical valence EXPLORE IN 3D • Generate a 3D view from your 2D sketch • Ball-and-stick, space-filling, and stick representations • Rotate and zoom IMPORT & EXPORT • Export PNG, SVG, SMILES, MOL, and SDF on device • InChI and IUPAC names require an internet connection via PubChem (NCBI) • Import SMILES and MOL/SDF files • Search PubChem by name, CID, or SMILES • Import PDB structures from RCSB for 3D viewing (3D viewer; not editable in 2D) MOLECULE INFO • Molecular formula, molecular weight, and DBE • Autosave drafts; dark mode and editor settings CHEMISTRY DATA DISCLAIMER Names, structures, and properties from this app or third-party sources (including PubChem) are provided for informational and educational purposes only.
