Typically, you will be given an NMR spectra and a molecular formula (sometimes an IR spectra will be provided). Edit. lbellop. IR and NMR Introductory Practice Problems Eight "starter" problems for using IR and 1H-NMR spectra to identify organic compounds. I have put together a few ideas that might make this process a bit easier. 1. 11. ALL THE BEST… Answer the following questions and then press 'Submit' to get your score. NMR practice DRAFT. 180 seconds . by lbellop. Most NMR questions on an exam involve determining a specific structure rather than memorizing and repeating various NMR values. Interpretation of spectra is a technique that requires practice - this site provides 1 H NMR and 13 C 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. ... 25 Questions Show answers. 50% average accuracy.
