Nuclear magnetic resonance (NMR) spectroscopy has a storied history. Edward Purcell and Felix Bloch developed the NMR technology in the late 1940s, for which they earned a Nobel prize in physics. The principle underlying this approach is that radio waves excite intramolecular magnetic fields around atomic nuclei, resulting in chemical shifts and changes in resonance frequency.
