    The isomer shift calibration constants have been calculated for 57.60 keV in 127I and for 27.72 keV in 129I resonant transitions by density functional theory. The NaI compound was used to set the origin of the scales in both cases. On the basis of the existing experimental data, the following values for the calibration constants were obtained: R )- 0.057(2) mm s-1 au3 for 127I and R ) +0.164(4) mm s-1 au3 for 129I. Spectroscopic electric quadrupole moments for the ground state of the above nuclei have been calculated as byproduct. The quadrupole moments Qg (127) ) -0.764(30) b and Qg (129) ) -0.731(3) b were obtained for 127I and 129I, respectively.
