Integrated 3D Molecular Editor and Viewer
The built-in 3-D editor allows users to draw arbitrary molecules from an intuitive click-and-drag interface with support for rotation, translation, and zooming. Clean-up automatically adds hydrogens and idealizes bond lengths and angles. Bond lengths, angles, and dihedrals may be displayed and adjusted. Fragments can be inserted, translated, and rotated.
Existing structures in XYZ, mol, or PDB format can be imported. The editor also allows for chemical information lookup, Huckel orbital calculations, and display of symmetry elements on structures.
Support for Popular Computational Engines
WebMO Basic supports most popular computational chemistry engines including: Gamess, Gaussian, MolPro, Mopac, NWChem, Orca, PQS, PSI, Q-Chem, TeraChem, Tinker, Quantum Expresso, and VASP
Supported calculation types include: molecular energy, geometry optimization, partial charges, bond orders, vibrational frequencies and spectra, excited states and UV-Vis spectra
Built-in Support for Mechanics and Huckel MO Calculations
WebMO Basic includes built-in support for molecular mechanics calculations, symmetry analysis, and Huckel molecular orbital calculations.
These basic calculations are available without using a separate computational chemistry program.
Graphical and Tabular Presentation of Results
The 3-D viewer allows one to rotate, translate, and zoom the molecule, as well as display bond lengths, angles, and dihedrals. Partial charges and the dipole moment are visualized on the structure.
Tables of energies, thermochemistry results, rotational constants, vibrational frequencies, etc. are presented. The program raw output is also available.
Visualization of Normal Modes and Spectra
WebMO Basic run jobs to calculate infrared, Raman, VCD, UV-Vis, and NMR spectra of molecules. the results are parsed and displayed both as energy level tables and as spectra. Vibrational normal modes are display either with arrows to indicate atom motions or as animations.
The displayed spectra are linked to the molecular image. Clicking on an infrared peak will display its associated normal mode. Clicking on an NMR peak will highlight the associated atoms.
Realistic NMR spectra can be displayed using estimated or calculated proton splittings.
Visualize Symmetry Elements
WebMO Basic can determine the point group of any molecule and display its symmetry elements, or any subset of symmetry elements.
A nearly symmetric molecule can also be symmetrized, which is useful prior to a calculation in order for the program to take advantage of the molecular symmetry.
Connection to Free External Databases
WebMO Basic can access and display results from a variety of external databases including PubChem, ChemSpider, NIST WebBook, Sigma-Aldrich, NMRShiftDB, and SDBS Spectral Database.
Once a molecule is imported or drawn, WebMO is a portal for displaying research, thermodynamic, safety, pricing, and spectral information available in these free databases.
Job Manager for Job Organization and Control
The Job Manager functions like an email inbox for your computational chemistry jobs.
Completed, running, and queued jobs are listed. Completed jobs may be downloaded. Existing jobs from other sources may be imported.
Phone/Tablet Support via the Free WebMO App
Support for Apple and Android phones and tablets is available using the free WebMO app.
Build molecules using an integrated editor, or import molecules by name. Lookup chemical information. Submit jobs to a WebMO server, and view calculated results.
All WebMO administration is performed via a menu-based web interface.
Add, edit, disable, or delete WebMO users. View, download, or delete jobs from WebMO users. Limit CPU time on a per job or cumulative basis. Configure computational chemistry program settings. Configure system and WebMO settings.
