NMR, Mass Spectrometry, and Infrared (IR) Spectroscopy

Nuclear magnetic resonance (NMR) spectroscopy takes advantage of the spin states of protons (and, to some extent, other nuclei) to identify a compound. Electrons can have one of two spin quantum states, which we designated as and . These spin states have equal energy in the absence of an applied magnetic field.
