In this NMR handout, you will get practice interpreting NMR spectra. Refer to the NMR tutorial/theory for chemical shifts and descriptions of peak splitting. There are 4 NMR problems. For each problem, you have been given the chemical formula as well as the IR and NMR spectra. Draw the structure for each unknown compound and provide sufficient reasoning as to why you think it has that structure. To get full credit, determine the structure of the unknown compound, calculate the...

show the calculations for, the degree of unsaturation, assign the
IR spectrum peaks, assign the 13C NMR peaks, assign the 1H NMR
peaks, and draw the structure for the unknown compound.
CHIM 245 Spectroscopy Problem Set #2 In this problem set there are two unknown compounds. You are provided with the formula, IR spectrum, "C NMR spectrum, and 'H NMR spectrum for each compound. Each unknown is worth 10 points, with an...
Draw the 1H NMR spectra you would expect for the following
compound. Note that you must put the peaks at the proper range of
chemical shift, with proper integral labeled below the peak, and
the proper spin-spin splitting.

4. Consider the following two diastercomers: Both compounds generate 'H NMR spectra with the following signals: A multiplet between 7.20-7.63 ppm with an integration of 5H Two separate doublets between 5.70-6.50 ppm, each with an integration of 1H A singlet around 1.30 ppm with an integration of 9H Despite the similarities, how could you differentiate between the H NMR spectra of these isomers? 5. Assign each set of protons to their appropriate signals in the 'H NMR spectrum shown below....
