| Research Abstract |
The Cavity Ringdown(CRD) spectrometer combined with the discharged nozzle was constructed in the University of Tokyo and Kagoshima University. Because CRD spectrometer is severely affected by reflectivity of mirror, the apparatus in Kagoshima was installed in clean room to keep out the ash from the volcano.New type slit nozzle was installed in new spectrometer to prevent the sample gas from diverging outside the optical axis. High-level ab initio calculation of the HO_3 radical was performed by using MRCI. The obtained potential energy surface of HO_3 reproduces experimental results well. The equilibrium structure of the HO_3 radical was determined by using the vibration-rotation coupling constants, which was obtained from the potential energy surface.
