This database contains the hyperfine parameters of a number of different iron minerals typically investigated in Environmental sciences. To use the search function, simply insert a range of different values (i.e. minimum and maximum) and use the search buttons to refine the table. Currently you can only search values for one specific parameter at a time rather than a combination of different parameters.

Ox. State = oxidation state, T = temperature, δ = isomer (chemical) shift ΔE_Q = quadrupole splitting, ε = quadrupole shift (only applies for sextets), B_hf = Hyperfine magnetic field, Site ID = Site identity/Total sites (i.e. if the value is 1/2 then this phase is just 1 of 2 sites which should be identified for a reliable agreement of phase identity), Reference = direct URL to the source of the parameters.
