WebMO

Computational chemistry without the command line. WebMO puts a molecular editor in your browser and runs state-of-the-art chemistry codes on Sagehen behind the scenes.

How it works

1

Build your molecule

Draw structures in a point-and-click 3D editor, or import them from standard file formats.

2

Choose a calculation

Pick from predefined job types (geometry optimization, frequencies, transition states) with sensible defaults, powered by Gaussian on the cluster.

3

Visualize results

Orbitals, vibrations, and optimized geometries render right in the browser when the job finishes.

Proven in the classroom

Pomona’s computational chemistry courses run on WebMO: students go from drawing a molecule to interpreting quantum chemistry results in a single lab session, no Linux experience required. Instructors: we’ll set up class accounts and tailor job types to your syllabus.

For research

WebMO is a fast on-ramp; labs doing docking, molecular dynamics, or large screening campaigns typically graduate to running Gaussian and other codes directly through Slurm. We’ll help you make that jump when you’re ready.

Getting access

WebMO accounts are set up on request for courses and research groups. Email us and we’ll have you running calculations the same week.

Chemistry, meet computing

Request WebMO access for your class or lab, or ask how computational chemistry could fit your research.
