Description

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

Can’t do much of anything

Rainbound on

No useful instructions. I can stick atoms together in random arrangements, that’s all.

Crashes on iPad 10

AceticAcid on

Great app, but the latest update is crashing on iPad 10. It happens upon immediately opening, so it’s completely unusable. I have forced the app to reset, checked for an update, uninstalled/reinstalled, and reset the device.

The premium was a SCAM

Suzhynes on

i really enjoyed this game and would’ve given it five stars, BUT I DECIDED TO GET THE PREMIUM AND IT DID ABSOLUTELY NOTHING!!! GIVE ME MY MONEY BACK OR ELSE

Great for students!

Bramble Head on

As a student I am constantly referring back to this app to help give myself an idea of a particular molecules reactive sites, it’s also really great to understand the planes that molecules are in!

Totally pro results

C.Clifford on

As good as much more expensive comp chem packages. Does what you probably need done anyhow, ESP, orbitals with occupancy, MM, etc.

Great app to visualize molecules and calculate basic properties

Riifaa on

Very useful for visualizing molecules in 3D. Great tool for teaching chemistry to students!

10/10

Will_Cleve on

Thank you guys for making this app free, it has helped me tremendously

Rich functionality, intuitive interface

Euler Wiles on

Nice array of functionality with an intuitive interface. There is a decent variety of information that you can obtain about a molecule; Pm6 calculation results can be generated.

Very good but.....

eno1ate on

This is a good app however it always crash.This is totally not enjoyable when using the app of this kind.

Best $5 I ever spent

nycqzbw on

Would’ve paid $20 lol
