In this talk, I will introduce the specificities of nuclear magnetic resonance spectroscopy in pulsed magnetic fields (PFNMR) above 45 T using non-destructive pulsed magnets [1]. These techniques require specific developments of custom pulsed magnets [2] and experimental setups. Due to the challenging conditions of pulsed magnetic fields, the measurable physical parameters are limited. I will explain the possible studies [3,4] and limitations of pulsed fields for NMR studies. These limits are due to both the short experiment duration and the limitations of RF techniques.
