The present study reports the experimental results and a theoretical model, based on short‐range order and electronic charge transfer from Ti to Fe, to explain the dependence of the isomer shift on the iron content in  &bgr;‐Ti(Fe) solid solution. The theoretical expression reported here for the isomer shift depends on three different fitting parameters which take into account the electronic‐charge transfer, and has been fitted with the experimental data for samples containing 3–18 at. % Fe.
