Dipole moment functions for electronic transitions from ion-pair states of the second tier of molecular iodine

The emission spectra caused by the transitions from the ion-pair states f0(g)(+) and G1(g) of the I-2 molecule are obtained by excitation of individual rovibronic levels of the molecule by the method of optical-optical double resonance. The emission spectra from the state F0(u)(+) populated due to collisions I-2(f) + I-2(X) are also measured. By modeling the experimental emission spectra, the dipole moment functions for the electronic transitions f0(g)(+)-BOu+, AO(u)(+), and B"0(u)(+); G1g-AO(u)(+) and B"0(u)(+); and F0(u)(+)-X0(g)(+) and a'0(g)(+) of the iodine molecule are reconstructed.
