Delivering The Vision Of An Online Database Of Nmr Spectra

2,130

Published on

ChemSpider is an online database of over 20 million chemical compounds sourced from over 300 different sources including government laboratories, chemical vendors, public resources and publications. Developed with the intention of building community for chemists ChemSpider allows its users to deposit data including structures, properties, links to external resources and various forms of spectral data. Over the past three years ChemSpider has aggregated almost 3000 high quality NMR spectra and continues to expand as the community deposits additional data. The majority of spectral data is licensed as Open Data allowing it to be downloaded and reused in presentations, lesson plans and for teaching purposes. Using the spectral data as a basis a web-based game, www.spectralgame.com, has been developed where players try to match molecules to various forms of interactive spectra including 1D/2D NMR. Each correct selection earns the player one point and play continues until the player supplies an incorrect answer. The spectra are displayed using JSpecView, an Open Source spectrum viewing applet which affords zooming and integration of JCAMP spectra. Players of the game provide both active and passive feedback regarding the quality of the spectral data resulting in crowd sourced curation and validation of the data. This presentation will provide an overview of ChemSpider and our mission to provide access to a free integrated database of various forms of spectral data.
