N2 - This paper deals with the interpretation of the Mössbauer effect (ME) of the 28 keV level in I129 and the analysis of the deduced constants in terms of chemical structure and lattice dynamics. The calculation of the magnitude and sign of e2qQ, the η parameter and the isomer shift from the quadrupole splitting spectrum is described. These parameters are directly related to the p electron population in iodine. The effect of the behaviour of the anisotropic recoilless fraction f on the various Δm transition intensities is demonstrated. Illustrations of the application of the ME in I129 for the structural determination of some tellurium compounds are given. CrI3 is cited as an example of a magnetic iodine compound and its spectra above and below the Curie temperature are analyzed. Finally, possible trends for future studies of the ME in I129 are outlined.
