Accessing External Databases
WebMO can serve as a portal for accessing information about molecules from other databases including:
- PubChem
- ChemSpider
- NIST Webbook
- Sigma Aldrich
- NMRShiftDB
- SDBS Spectral Database
From the Build Molecule or View Job page, choose Lookup: Databases and select the desired database. WebMO will lookup the displayed molecule and display the result in a new tab. Links in the displayed page can be followed for additional information.
