WebSpectra is a World Wide Web site at UCLA through which organic chemistry students have convenient access to a library of problems in NMR and IR spectroscopy, ranging in difficulty from introductory to advanced. Students are presented with high-resolution spectra of unknown compounds in addition to the molecular formula. Expandable one-dimensional 1 H and 13 C NMR spectra are available for all problems and many also include IR, DEPT NMR, and/or COSY NMR spectra. In addition to the spectral problems, WebSpectra provides instructional documents on basic NMR and IR spectroscopy concepts. There is also an IR comparison tool that allows overlays of spectra and a search engine that allows students to locate specific types of compounds based upon name, formula, or functional group. The design and capabilities of this Web-based educational tool are described in this paper.
