The E 0^+_g ion-pair state of I_2 molecule may be excited by the optical-optical double resonance (OODR) via the valence state B 0^+_u, I_2(X 0^+_g) + hv_1 → I_2 (B 0^+_u ) + hv_2 → I_2 ( E 0^+_g ). Emission spectra of pure I_2 vapor selectively excited in this way show not only ransitions from the E 0^+_g state, but also D 0^+_u → X 0^+_g transition in the near ultraviolet. Typically the populated levels in the D 0^+_u state are located less than 300 cm^{-1} below the laser-excited level. In this contribution we examine rotationally resolved Fourier-transform spectra of the D 0^+_u → X 0^+_g emission following OODR excitation of various E 0^+_g {v, J} levels with single mode cw dye lasers. We show that the E 0^+_g → D 0^+_u population transfer obeys the J_D=J_E ^+_- 1, 3, 5 ... propensity rule. Transfer to the J_D=J_E ^+_-1 levels is the most probable although in some cases, J_D=J_E-1 and J_D=J_E+1 have significantly different populations.
