Transcript of Building a Community Resource of Open Spectral Data
Building a Community Resource of Open Spectral Data
If there were an online DB of spectra.. Reference data
Could dramatically reduce rework
Excellent teaching resource
Opportunity for crowdsourced review and annotation of data (“Wikipedia for spectra”)
Other…
Where is chemistry online? Encyclopedic articles (Wikipedia) Chemical vendor databases Metabolic pathway databases Property databases Patents with chemical structures Drug Discovery data Scientific publications Compound aggregators Blogs/Wikis and Open Notebook Science
And where are spectra online?

What’s in the way of “Open Spectra”
Spectral databases are revenue generators Intellectual property Scientist versus organizational ownership Legal risks It’s generally “work” to release data
Confusion about “Free Data” versus “Open Data” – some people will provide “Free Data”, some will provide “Open Data”. They are different
A Pragmatic Vision“Build a Structure Centric Community to
Serve Chemists”
Integrate chemical structure data on the web Create a “structure-based hub” to information and
data Provide access to structure-based “algorithms” Let chemists contribute their own data Allow the community to curate/correct data
We Answer Questions for Chemists Questions a chemist might ask…
What is the melting point of n-heptanol? What is the chemical structure of Xanax? Chemically, what is phenolphthalein? What are the stereocenters of cholesterol? Where can I find publications about xylene? What are the different trade names for Aspirin? What is the IR spectrum of Benzoic Acid?

Linked to vendors, safety data, toxicity, metabolism

ChemSpider Today
24.8 million structures 400 data sources Grows daily Community annotation and curation
We curate, edit, change, enhance data daily

Spectra on ChemSpider
Sources of Spectra
Sourced from online sources with permission
Private collections
The MAJORITY deposited by ChemSpider users
Spectral Uploading
Locate the structure of interest and deposit spectrum
Spectral Uploading Various types of NMR spectra supported
Spectral formats supported
Spectra may be uploaded as JCAMP-DX format
Graphical formats such as JPEG, PNG, GIF
PDF files
Multiple Spectra for One Structure
ChemSpider ID 24528095 H1 NMR
ChemSpider ID 24528095 C13 NMR
ChemSpider ID 24528095 HHCOSY
ChemSpider ID 24528095 HSQC
ChemSpider ID 24528095 HMBC
Deposit spectra against new structure
If a NEW compound has spectral data then deposit the structure onto ChemSpider first

Building Other Spectral Games!
We would like to build other forms of the spectral game. The database is presently very rich in NMR data
There are presently 101 Infrared Spectra 46 Raman Spectra We would like more!!!
Invitations
Spectral data are welcomed from associated syntheses, lab experiments etc
Upload structures, spectra, analyses etc to ChemSpider to share with the community
Use www.SpectralGame.com and encourage your students
Thank you
