摘　　要：Na2 2 3 Πg 和 33 Πg 态在 3486 0cm-1(相对基态Te)和 3s+3d解离限之间的Ω =0 ,1,2能级进行了脉冲激光微扰增强双共振探测 .观测到两个态之间强烈的相互微扰 .给出忽略微扰情况下Ω =0能级的Tv 和Bv.The Ω= 0,1,2 levels of the Na 2 2 3Π g and 3 3Π g states in the energy region between 34860 cm -1 above the T e 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 T v and B v values are given for the Ω=0 component without deperturbation.
