Label the significant peaks in the IR and NMR spectra. When analyzing the signals in the 'HNMR, be sure to include all appropriate information. For example: 3H, singlet, 0 neighbors, and c (the letter referring to the corresponding unique type of hydrogens that were labeled in the structure). It is recommended to provide more analysis for each signal than what is described above, when necessary, such as labeling any coupling constants if any are provided For NMR label each peak...

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...

Organic Chemistry 1 Lab Fall 2019 Spectral Set 2 Due 10/29 - 10/31/2019, during regular lab time. For each set of spectra, label the major IR absorptions, deduce a workable formula, and calculate the DBE for that formula. Then using the splitting patterns and integrations, determine the structure of the molecule responsible for the spectra. Be sure to label each NMR signal like we did in class. S = singlet, d = doublet, t= triplet, q#quartet, p = pentet, n=nonet,...
