Production of transient molecules and their detections by using highly sensitive spectroscopic methods and a new type slit nozzle

构建了激光诱导荧光（LIF）和腔衰荡（CRD）光谱仪与脉冲放电喷嘴相结合的结构。通过监测CN自由基的吸收光谱强度，对该装置进行了优化。结果表明，该光谱仪具有足够的灵敏度，可以观测自由基的光谱。构造了一种新型的缝状喷管。目前，我们正尝试用CRD光谱仪和新型狭缝喷嘴观察稀有气体-分子/自由基-分子配合物，如h2o - oh或Ar-CN的电子跃迁谱。

The Laser Induced Fluorescence (LIF) and Cavity Ringdown (CRD) spectrometers combined with the pulsed discharged nozzle have been constructed. This apparatus were optimized by monitoring the intensities of the absorption spectra of the CN radical. It was confirmed that these spectrometer have enough sensitivity to observe spectra of radicals. A new type slit discharge nozzle was constructed. Now, we are trying to observe electronic transition spectra of rare gas-molecule/radical-molecule complexes, such as H_2O-OH or Ar-CN by using the CRD spectrometer and new type slit nozzle.
