- W976425948 abstract "受激拉曼激发H2（0,1）基态的Q支得到H2（1,1）能级。在室温条件下,利用反斯托克斯拉曼散射（CARS）探测技术测量了碰撞能量合并（EP）过程H2（1,1）＋H2（1,1）→H2（2,J）＋H2（0,J″）及H2（1,1）与H2（1,J）转动能级间的碰撞转移速率系数。扫描CARS谱表明在H2（1,1）能级的碰撞能量转移过程中,仅使（2,1）,（1,0）和（1,2）的振转能级得到布居。从H2（2,1）能级的时间分辨CARS强度的半对数描绘得到其退布率为（2.8±0.5）×105 s-1。用n1,n2,n3和n4,分别表示（1,1）,（2,1）,（1,0）和（1,2）能级上的布居数密度,对H2（1,1）能级的时间分辨CARS轮廓的形状进行理论模拟,并与实验结果进行比较,确定n1/n2=4.2。从扫描CARS谱的峰值得到n3/n2=1.2和n4/n2=1.0。确定被碰撞转移的H2有0.31处在v=2上,而在v=1上有0.69。碰撞能量合并的速率系数为（7.5±1.4）×10-14 cm3 s-1。对实验结果进行了讨论。" @default.
