| Abstract: | The emission spectra caused by the transitions from the ion-pair states and f0 g + and G1g of the I2 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 I2(f) + I2(X) are also measured. By modeling the experimental emission spectra, the dipole moment functions for the electronic transitions f g + -B0 u + , A0 u + , and B″0 u + ; G1g-A0 u + and B″0 u + ; and F0 u + -X0 g + and a′0 g + of the iodine molecule are reconstructed. |
