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). CeHioO2 3H NO PPM 160 200 20 220 180 120 PPM 100 140 80 60 40 VEM
Suggest a composition for the halogen compound whose mass
spectrum is shown below and assign the labeled peaks.
