| 摘 要： | 利用微波放电Cl2/He等离子体作为Cl源，对反应NCl(a1Δ) + I(2P3/2)→NCl(X3Σ) + I(2P1/2)进行了实验研究，得到了较大的I(2P1/2)自发辐射荧光信号，检测到NCl(a1Δ，b1Σ)自发辐射荧光光谱在存在少量I(2P1/2)下发生的显著变化，其中NCl(a1Δ)自发辐射荧光信号降低，同时由于I(2P1/2)的作用，NCl(b1Σ)自发辐射荧光信号大幅度增加。在考察各反应气体流量对I(2P1/2)自发辐射荧光信号的影响时发现，在本次实验条件下，各种气体的最佳流量：He为1～4mmol/s, I2为0.01～0.03mmol/s, Cl2为1.0mmol/s左右,而HN3流量略大于Cl2流量时信号升高幅度开始变缓，约为Cl2流量的两倍时信号不再有显著的变化。

| Abstract: | NCl(a1Δ) /I（2P3/2）System was studied using microwave discharge Cl2/He plasma as Cl atoms source. Strong I (2P1/2) radiation at 1 315nm was obtained. The considerable changes of NCl (a1Δ) and NCl (b1Σ) radiation at 1 077nm and 665nm respectively were observed when a little amount of I2 was injected into the flow of Cl and HN3, namely NCl (a1Δ) radiation at 1 077nm decreased rapidly while NCl(b1Σ) radiation at 665nm increased rapidly due to the reactions NCl(a1Δ)+I(2P3/2)→ NCl(X3Σ)+I(2P1/2) and NCl(a1Δ)+I(2P1/2)→NCl(b1Σ)+I(2P3/2). The intensity dependence of I (2P1/2) radiation at 1 315nm on He, Cl2, HN3 and I2 flow rate was investigated. The results show that the optimum flow rate for gases of He, I２，Cl２ and ＨＮ３ are 1～4, 0.01～0.03, 1 and 1～2mmol/s respectively. |
