摘要
用流动余辉技术研究了惰性气体亚稳态原子He(2~3S、Ne(~3P_(2.0))、Ar(~3P_(2.0)与CS_2分子的能量转移反应,测定了反应产物CS(A^1∏)态各振动能级的初生态分布.由惊奇度分析可以证实,振动能级的粒子数分布是部分反转的,并从稳态条件求出了CS(A^1∏,v′)与He、Ar碰撞时的V—T及V—V转移速率.
Using discharge-flowing afterglow method, We have studied energy transfer reactions of metastable rare gas atoms, He(~3S)、Ne(~3P_(2,0))、Ar(~3P_(2,0)) to CS_2 molecule, and measured the nascent vibrational distribution of the product CS(A^1Ⅱ). It is confirmed by 'surprise' analysis that vibrational population of product is inverse partially. We calculated the V-T and V-V energy transfer rates of CS(A^1Ⅱ,v')in collision with He、Ar under the stationary condition.
