With NMR, an Almost-Zero Magnetic Field is Even Better

In May of this year, a team of Berkeley Lab and UC Berkeley scientists, led by chemist Alex Pines of the Materials Sciences Division and physicist Dmitry Budker of the Nuclear Science Division, announced chemical fingerprinting with NMR in a zero magnetic field. It turns out that the remaining ambiguity that zero-field NMR leaves in the determination of chemical groups can be removed by applying a very small magnetic field after all. In a recent Physical Review Letters the team describes this and the other advantages of their new technique for near-zero-field nuclear magnetic resonance.
