摘要

We used the perturbation-facilitated optical-optical double resonance technique to access the ungerade ion-pair states of I_2 using the (1+1) photo-excitation sequence throught he B~III(0_u~+)-cl_g parity mixing states. By analyzing the second step of the double resonance to the F0_u~+(~3P_1) states, the g-u coupling schemes were elucidated in the intermediate B~3III(0_u~+)-cl_g state. We were also able topopulate the #delta#2_u(~3P_2) state through the g-u mixing state, and to improve its molecular constants. The interference effect between the paraller #gamma#l_u(~3P_2-cl_g and perpendicular #delta#2_u(~3P_2)-cl_g transitions was used to derive the ratio of their electronic transition moments, (#mu#_||~e/#mu#_perpendicular~e) approx 5.5.
