Nuclear magnetic resonance is an absorption spectroscopy whose foundation is the absorption of radio frequency energy, by a magnetically active nucleus. The nucleus is oriented in a magnetic field and due to the absorbed energy, changes its orientation. Barcelona Research Center in Multiscale Science and Engineering has a Bruker NMR Ascend 400 of 400MHz equipped with two probes for a liquid and solid samples. The software Topspin was designed with a highly intuitive interface and is the industry standard for NMR data analysis and the acquisition and processing of NMR spectra.
