利用相干反斯托克斯拉曼谱（CArtS）分析了H2与Li2（A^1∑u^＋）-H2碰撞的振转态布居分布。扫描cARS谱表明了在能量转移过程中H2的v=1，2，3振转能级上得到布居，由CARS峰值得到两个可能的布居数比值，通过解速率方程组并通过时间分辨CARS轮廓模拟，确定了实际的布居数之比。得到了H2在V=1，2，3能级上的布居数比为0．48，0．36，0．16，平均转移能配置的相对值〈ft〉，（fvib〉，〈fr〉分别为0．50，0．47，0．03，能量主要配置在平动和振动上，支持Li2-H2直线式碰撞传能机制。

Coherent anti - Stokes Raman Spectroscopy （ CARS} ha been used to analyze the vibrotational state distribution of H2 after energy transfer with Li2 （A^1∑u^＋）.The scanned CARS spectra reveal that during energy transfer processes H2 molecules are produced at the V = 1,2 and 3 vibrational levels. From scanned CARS spectral peaks two possible population ratios are obtained. Through shape simulations of the time resolved CARS profiles under a kineti model, the actual population ratios are determined. The H2 molecules produced by the energy transfer process are O. 48 populated at the V = 1 level, 0.36 at V = 2 and 0.16 at V = 3. The relative fractions （〈 fv 〉 , 〈 fvib 〉 , 〈 fr 〉） of average energy disposal are derived as （ 0.50, 0. 47, 0.03 ）, having major vibrational and translational energy release. This consequence supports a collinear collision geometry in Li2 - H2 energy transfer.
