The pressure‐dependence of the zero‐field splitting of the S =10 ground state of the single‐molecule magnet Mn 12 ‐acetate was studied by inelastic neutron scattering (INS) at hydrostatic pressures up to 12 kbar (see picture). The anisotropy increases with increasing pressure, and a pressure‐dependent minority species of Mn 12 ‐acetate was observed. The increased anisotropy arises from increases in the single‐ion anisotropy of the Mn 3+ building blocks.
