Junhui Shi, Suvi Ikäläinen, Juha Vaara, Michael V. Romalis

摘要:

核自旋旋光(NSOR)是近年来发展起来的一种利用光的偏振旋转代替通常的长程磁场来探测核磁共振的新技术。NSOR信号依赖于与虚拟光激发的超精细相互作用,提供了有关核化学环境的新信息。我们使用一个多通光学细胞进行第一次精密测量的NSOR信号的范围内的有机液体,并发现质子信号之间的明确区别,为不同的化合物,与我们以前的预测一致。详细的第一性原理量子力学NSOR计算被发现是在良好的协议与测量。

英文摘要:

Nuclear spin optical rotation (NSOR) is a recently developed technique for detection of nuclear magnetic resonance via rotation of light polarization, instead of the usual long-range magnetic fields. NSOR signals depend on hyperfine interactions with virtual optical excitations, giving new information about the nuclear chemical environment. We use a multi-pass optical cell to perform first precision measurements of NSOR signals for a range of organic liquids and find clear distinction between proton signals for different compounds, in agreement with our earlier predictions. Detailed first principles quantum-mechanical NSOR calculations are found to be in good agreement with the measurements.
