一种零、超低磁场下的核磁共振仪器
Instrumentation for nuclear magnetic resonance in zero and ultralow magnetic field
摘要：
我们审查仪器核磁共振（NMR）在零和超低磁场（ZULF，低于0.1 $μ$ T）的检测是基于一个低成本，非低温，自旋交换弛豫（SERF）$^{87}$ Rb原子磁力计。对于低于1 kHz的信号频率，典型的灵敏度为20-30 fT/Hz $^{1/2}$，NMR线宽范围从Hz一直到几十mHz。这些特性使得能够精确测量化学信息的核自旋-自旋耦合以及超低磁场中的核自旋进动。
英文摘要：
We review instrumentation for nuclear magnetic resonance (NMR) in zero and ultra-low magnetic field (ZULF, below 0.1 $μ$T) where detection is based on a low-cost, non-cryogenic, spin-exchange relaxation free (SERF) $^{87}$Rb atomic magnetometer. The typical sensitivity is 20-30 fT/Hz$^{1/2}$ for signal frequencies below 1 kHz and NMR linewidths range from Hz all the way down to tens of mHz. These features enable precision measurements of chemically informative nuclear spin-spin couplings as well as nuclear spin precession in ultra-low magnetic fields.
