摘要: 以Cl/Cl2/HN3/He为基础的NCl(a1Δ)/I作为一种化学激光新的体系，氯原子产生的多少对该体系的研究是至关重要的。利用滴定法研究了微波解离氯分子的解离效率。用HN3/He滴定Cl，由光学多通道分析仪监测NCl(a1Δ)和NCl(b1Σ)辐射的荧光。发现微波解离氯分子的效率并不是想象的那样低，在较小的氯流量下，最高的解离效率可以达到100％。Abstract: For the system of Cl/Cl2/HN3/He which is the basis of concept of NCl(a1Δ)/I as a newly possible laser system, the amount of the production of chlorine atoms is essential and important to the system. In this paper, the dissociation efficiency of chlorine by a Microwave Generator is investigated by a versatile titration technique. The intensity of NCl(a1Δ) and NCl(b1Σ) emission is monitored by an OMA with the titration of mixture of He and HN3. The dissociation efficiency of chlorine by Microwave Generator is not low as expected, it is up to 100% at lower flow rate of chlorine and decreases with increasing chlorine flow rates.
