摘要
用2824～2838A波段的紫外激光,共振激励火焰中产生的自由基OH,检测它的离化信号,得到了紫外2830A附近OH的光谱带,它对应于X2π→A2∑(v=0→1)的跃迁。测量到的20多条谱线与火焰发射光谱结果符合极好。这种方法提供了一种检测自由基及诊断火焰的新途径。
Abstract
The radical OH produced in air-aeytilene flame resonantly excited by ultraviolet (UV) laser in 2824～2838A region. The enhanced ionization signals were detected. The spectral bard of radical OH was obtained in the vinicity of UV 2830A, corresponding to a transition of OH X2π→A2Σ(v=0→1). More than twenty spectral line were measured, which oonioide with previous data obtained from flame emmision speotroscopy well. This method has provided a way of radical determination and flame diagnosis.
