3/1/2018 Spectra Lab You have four spectra: 1H NMR, 13C NMR, IR, and Mass Spec. Working by yourself or with your partners answer the following questions 1. Identify the major peÄ ks provided in the IR spectrÄ from 4000-1500 cm1 coho 2. Identify the information in the 1H NMR? a. b. c. Signals - How many? Splitting - e.g., doublet Shifting -Does the shifting for each peak indicate a known functional group in the H NMR? e.g., benzene 3. Identify the information in the mass spectra data? a. Base peak b. Molecular ion peak c. Isotopes d. What is the mass of the compound? 4. Identify the information in the 13C NMR? Signals - How many unique carbon signals. Shifting -Does the shifting for each peak indicate a known functional group in the 13C NMR? e.g., benzene a. b. structure for the unknown. Taking all the information, you have gathered draw the correct
