WebSpectra Adenosine
Problems in NMR and IR Spectroscopy

Welcome to WebSpectra - This site was established to provide chemistry students with a library of spectroscopy problems. Interpretation of spectra is a technique that requires practice - this site provides 1H NMR and 13C NMR, DEPT, COSY and IR spectra of various compounds for students to interpret. Hopefully, these problems will provide a useful resource to better understand spectroscopy.

This project is supported by Cambridge Isotope Laboratories and the UCLA Department of Chemistry and Biochemistry.
