Nuclear Magnetic Resonance (NMR) is one of the most widespread and versatile spectroscopic probe of contemporary natural sciences. An application in high-pressure or experimental geo-sciences was however regarded unfeasible until recently. In this talk, I will summarize recent developments in both experiment and method of high-pressure small-scale NMR methods. These developments include the implementation of NMR-crystallographic methods using a combination of high- and low-resolution techniques as well as the opportunity for hydrogen or water quantification in in-situ DAC based experiments or nominally anhydrous minerals under ex-situ investigation.
