Spectroscopy: Shifting light with spin

Warren S. Warren1

NMR spectroscopy has changed enormously over the years, but signal detection has stayed the same since the technique was invented. The latest thinking literally shines a new light on things.

Sixty years ago, the forefront of speculative physics research included the nascent field of nuclear magnetic resonance (NMR). Physicists placed atomic nuclei in a strong, constant magnetic field and then watched the voltages induced in a coil when the nuclei were perturbed with weak, finely tuned radio waves.
