Abstract:

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. 

Key words: NMR, ultra-high magnetic field, field mapping, shielding effect
