This article deals with the implementation of Nuclear Magnetic Resonance (NMR) experiments in pulsed magnetic fields at the pulsed-field facility of the Laboratoire National des Champs Magnetiques Intenses and its application to the high-T-C superconductor YBa2Cu3O6.51. The experimental setup is described in detail, including a low-temperature probe head adapted for pulsed fields. An entire paragraph is dedicated to the discussion of NMR in pulsed field and the introduction of an advanced deconvolution technique making use of the induction voltage in an additional pick-up coil. The Cu-63/Cu-65 NMR experiments on an YBa2Cu3O6.51 single crystal were performed at 2.5 K during a field pulse of 46.8-T-amplitude. In the recorded spectrum the Cu-63 center line and high-frequency satellites as well as the Cu-65 center line are identified and are compared with results in literature.
