NMR goes optical Physicists in the US have invented a new form of nuclear magnetic resonance (NMR) that could significantly improve the resolution and sensitivity of the technique. The method, developed by Michael Romalis and co-workers at Princeton University, involves shining a laser on a sample and measuring how it rotates the plane of polarization of the beam. The new technique could lead to real-time two-dimensional imaging of samples, with a resolution limited only by light diffraction.
