Organic Spectroscopy

The course covers infrared (IR) spectroscopy, mass spectrometry, and nuclear magnetic resonance (NMR) spectroscopy, the latter of which is the main focus. Topics covered in the NMR spectroscopy part of the course include chemical shifts, spin-spin coupling, dynamic effects in NMR spectroscopy, and 2D NMR spectroscopy (COSY, HMQC, HMBC, TOCSY, NOESY, ROESY).
