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...
Spectroscopy Problems For each problem, you must: 1) Calculate the degree of unsaturation. 2) Assign the principal IR absorption bands above 1500 cm-1 3) Draw the structure of the compound 4) Label the protons on your structure with letters and assign them to peaks on the NMR spectrum (see the example below). в OHD 3.5- 3. 2.5 1.0 PPM 0.5 Each problem contains the formula of the compound, the IR spectrum (with axes in cm vs. % transmission), and the...
