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

HOW TO GET STARTED • Begin using the app free with all features available. After 3 days, select either a weekly or annual plan. • Paste the job description, and PrepLine generates behavioral, role-specific, and fit questions tailored to that role, seniority, and company. • Allow PrepLine to review your responses and provide immediate feedback. WHAT YOU GET • Within seconds, each answer receives a score out of 10, without delays or queues. • STAR feedback: identify which of Situation (S), Task (T), Action (A), and Result (R) you achieved, plus guidance on what to add. • Strengthen your responses using feedback. This is not a template—your own story, revised to be effective, with blanks where only you know the figures. • As you practice, observe your readiness score rise and note weak areas while there is time to adjust them. • Store multiple jobs you are interviewing for. Switch between them and resume where you stopped. • Avoid guessing what they will ask. Enter knowing. PRIVACY • No account or sign-up is required. Your job targets, answers, and scores remain on your device. To score a response, PrepLine sends that answer and the job details to its AI provider—this is the only data that leaves your phone. No third-party tracking occurs, and your job search is never sold.
