“…The corresponding SNR, corrected for a differing number of scans and digitisation frequencies (see eq.1), of the paraffin oil signal before and after heating as well as of the hydride signal were found to be ζ 0 Res = 23674, ζ LH Res = 17158 and ζ LH FeHx = 7702, respectively. Assuming a hydrogen density of the precursor of n 0 Res = 0.0729(73) H/ Å3 [37][38][39], the hydrides' hydrogen density can be directly calculated to be n LH FeHx = 0.086(18) H/ Å3 . Using the equation of state from Narygina et al [40], the hydrogen concentration directly after the compound's synthesis at 35 GPa amounts to 3.9(3) H/unit cell and thus gives rise to about 0.95(5) H/formula unit, reasonably close to the inferred hydrogen content from X-ray diffraction experiments for the iron monohydride (x = 1).…”

High-pressure metal-hydride (MH) research evolved into a thriving field within condensed matter physics following the realisation of metallic compounds showing phonon mediated near roomtemperature superconductivity. However, severe limitations in determining the chemical formula of the reaction products, especially with regards to their hydrogen content, impedes a deep understanding of the synthesized phases and can lead to significantly erroneous conclusions. Here, we present a way to directly access the hydrogen content of MH solids synthesised at high pressures in (laser-heated) diamond anvil cells using nuclear magnetic resonance (NMR) spectroscopy. We show that this method can be used to investigate MH compounds with a wide range of hydrogen content, from MHx with x=0.15 (CuH0.15) to x 6.4 (H6±0.4S5).
