We can use spectroscopy to determine the structure and functional groups in organic compounds. Lecture 20. Lecture 14. Organic Spectroscopy: Inadequate. The next focuses on using these three techniques together to determine the structures of organic compounds. The off-diagonal peaks, appearing always in pairs, indicate that the central CH2 group is coupled to the terminal CH2 and CH3 groups. We will be learning about how to use IR, UV/Vis, and NMR spectroscopy. h�bbd``b`:$��C+�`v ������ ��~ �� (English), Chem 203.
