Answer the following questions and then press 'Submit' to get your score. Hopefully, these problems will provide a useful resource to better understand spectroscopy. Spin-Spin Splitting in 1 H NMR. 13C NMR practice test problems. May 23, 2020 May 25, 2020 chemqueen. Welcome to WebSpectra - This site was established to provide chemistry students with a library of spectroscopy problems. 6 months ago. Enter the appropriate letter in the answer box to the right of each formula. 1.What splitting pattern in the 1 H nmr spectrum would you expect for the hydrogen atom(s) colored red in the compounds shown below? Question 1 . 12th grade . ... 25 Questions Show answers. For each example you should find the number of signals you expect, where they should show on the scale (chemical shift), and what shape they should be (splitting patterns). You will find a short table of useful chemical shifts at the end of the questions. Which molecule will produce the following spectra with 3 different H environment? 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. 11.
