Research Abstract

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.
