Recent developments in in situ nuclear magnetic resonance (NMR) spectroscopy under extreme conditions have led to the observation of a wide variety of physical phenomena that are not accessible with standard high-pressure experimental probes.However, inherent di- or quadrupolar line broadening in diamond anvil cell (DAC)-based NMR experiments often limits detailed investigation of local atomic structures, especially if different phases or local il barone wine environments coexist.Here, we describe our progress in the development of high-resolution NMR experiments in DACs using one- and two-dimensional homonuclear decoupling experiments at pressures up to the megabar regime.

Using this technique, spectral resolutions of the order of 1 ppm and below have been achieved, enabling high-pressure structural analysis.Several examples are presented that demonstrate the wide here applicability of this method for extreme conditions research.
