摘要 研究了超强磁场对于核磁共振样品中双原子分子中电子系统的哈密顿量的影响,并且给出了磁共振信号中由于外磁场与氢原子电子系统相互作用所产生的含有B02的修正项.基于核磁共振原理,获得了利用氢的NMR谱对超强磁场进行精确测量的理论依据,推导出了一种基于核磁共振技术的超强磁场测量公式,从而在理论上证明了对超强磁场进行精确测量是可行的. The effects of ultra-high magnetic field on Hamiltonian of electronic system of diatom molecule in NMR samples were studied. The interactions between the external magnetic field and the electronic system of the diatom molecule were shown to give correction terms for NMR signals that is proportional to B20. Given the result, we proposed a method to measure ultra-high magnetic field strength with NMR signals.
