The Ω = 0,1,2 levels of the Na2 2 3Πg and 3 3Πg states in the energy region between 34860 cm-1 above the Te of the ground state and the 3s+3d atomic limit have been probed by pulsed laser perturbation facilitated optical-optical double resonance(PFOODR)spectroscopy. Strong mixing of these two states has been observed. The Tv and Bv values are given for the Ω = 0 component without deperturbation. 相似文献

This paper reports our new observation of the , 13Δg (v = 2–4), and 23Πg (v = 2–8) states of 6Li7Li by continuous wave perturbation facilitated optical–optical double resonance spectroscopy. Combining our new experimental term values of 6Li7Li with the available experimental data of 6Li2 and 7Li2, molecular constants and potential energy curves by Rydberg–Klein–Rees and direct-potential-fit techniques have been determined. Born-Oppenheimer breakdown parameters of the Li2 13Δg and 23Πg states are calculated. 相似文献
