The CL reactions of Sr(~1S), Sr(~3P)+Cl_2 have been studied under single collision condition on a beam-gas apparatus in the pressure of range 10~(-5)—10~(-4) Torr.The temperature of the metal oven was about 1000K.The CL spectra of SrCl (A,B) and SrCl_2~* produced in the reactions of Sr, Sr~* +Cl_2 have been observed and analyzed. The CL spectra are always dominated by the monochloride emission while the subcontinuous emission of dichloride SrCl_2~* becomes stronger with increasing...

The CL reactions of Sr(~1S), Sr(~3P)+Cl_2 have been studied under single collision condition on a beam-gas apparatus in the pressure of range 10~(-5)—10~(-4) Torr.The temperature of the metal oven was about 1000K.The CL spectra of SrCl (A,B) and SrCl_2~* produced in the reactions of Sr, Sr~* +Cl_2 have been observed and analyzed. The CL spectra are always dominated by the monochloride emission while the subcontinuous emission of dichloride SrCl_2~* becomes stronger with increasing Cl_2 pressure. The experimental results show that the intensity of SrCl~* emission depends linearly upon both Cl_2 pressure and Sr number density. This means that SrCl~* is the direct product of single collisions. Whereas the quadratic dependency of SrCl_2~* intensity upon the Cl_2 pressure shows that it is produced in arreaction of SrCl+Cl_2, the same mechanism as BaCl_2~* produced in reaction of Ba + Cl_2~([4,5]).The total cross section for the removal of metal atoms in ground state Sr(~1S)and excited states Sr(~3p) by _2 molecules are 58~2 and 97~2 respectively. The relative photon yield of SrCl(A) produced by Sr(~1S) and Sr(~3P) reacting with Cl_2 is about Φ~*/Φ~0=115.

本文在束-气条件下研究了Sr(~1S),Sr(~3P)+Cl_2的化学发光反应。实验压力为10~(-5)~10~(-4)Torr,金属束炉温1000K左右。同时,观测和分析了Sr,Sr~*+Cl_2反应产物Sr(A,B)、SrCl_2~*的发光光谱。发现Cl_2压力(pcl_2)较低时,主要生成SrCl~*;而pcl_2增高时(>2×10~(-4)Torr),SrCl_2~*的发射光谱逐渐增强。实验结果表明,SrCl~*是单次碰撞的直接产物,其发光强度(I_(SrCl)~*)与pcl_2、Sr的原子密度均为直线关系,而I_(SrCl_2)~*与pCl_2成二次关系,表明SrCl_2~*是SrCl~*和Cl_2碰撞的产物,与BaCl_2~*的生成机理相同。由实验结果计算而得到的亚稳态Sr~*原子及基态Sr原子在Cl_2中的总消除截面分别为97±5(?)~2及58±5(?)~2。由此估计由亚稳态Sr~*及基态Sr与Cl_2反应生成SrCl(A)的相对光子产率为φ~*/φ~0=115。

The present paper reports a novel chemiluminescence (CL) system, iso-propylalcohol-ClO--H2O2. In basic medium, iso-propylalcohol can react with ClO- or H2O2 to produce CL emission. If iso-propylalcohol was initially mixed with ClO- and then H2O2 was added to the above mixed solution the CL intensity became greater. The kinetic process agreed with the index attenuation formula I(t) = 16exp(-0.21t), and the constant of attenuation speed was 0.21sec-1. The effects of reagent concentration, some metal ions and pH value of ClO- solution on the CL in tensity were studied. Acetaldehyde can enhance the CL intensity, and the enhanced CL intensity is proportional to the concentration of acetal-dehyed within the range of 5.0×10-10g/ml-1.0×10-6g/ml. Based on this result, we have developed a new CL method for the determination of trace acetaldehyde, with which some foreign inorganic ions as well as usual organic compounds do not interfere. The mechanism of the CL reaction has also been briefly discussed.
