Abstract
By considering Mössbauer data for ferrous ions in almandine, an unambiguous choice can be made between the two different models (White and Moore, 1972; Runciman and Sengupta,1974) recently proposed for the five 3d levels of ferrous ions in almandine. Based on the quadrupole splitting value and its temperature dependence, the model of White and Moore (1972) is definitely favored. The Mössbauer data indicate that the separation of the two lowest levels is about 1100 cm-1. This value enables considerably more precise estimates to be made of the crystal-field parameter and the crystal-field stabilizatlon energy.
