Problems in NMR and IR Spectroscopy

文字:[大][中][小] 手机页面二维码 2016/12/7     浏览次数:    
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.

Problems 
All problems contain 1H and 13C NMR Spectra 
Problems with additional spectra are marked:  IR Spectrum,  DEPT spectra, and  COSY spectrum.

Use the WebSpectra Search to locate specific types of compounds

IR Spectra may be compared in order to illustrate differences in absorption using the WebSpectra IR Comparison.
