The dipole moment functions of the iodine D′2_g A′2_u and D0⁺_u a′0⁺ _g transitions in the ranges of 3.04.8 and 3.14.1 Å have been determined for the first time by means of simulation of the luminescence spectra from the D′ v_D′ = 58, J_D′ = 39 and D, v_D = 13, 18; J_D = 26 rovibronic levels, respectively. The dipole moment functions of the iodine E0⁺_gB0 ⁺_u and D0⁺_uX0⁺ _g transitions have also been re-examined using a more perfect than employed earlier method of calibration of the spectral sensitivity function of the condenser/monochromator/detector system.
