Outline of Final Research Achievements

We developed a hot gas nozzle which can heat sample gas up to 1000K and achieved a photoelectron spectroscopy for vibrationally excited molecules. For evaluation of our new equipment, we measured photoelectron spectra for CO2 molecules at room temperature and 900K. For room temperature, we obtained similar photoelectron spectrum of CO2 molecules to the previous reported one, where band structure of symmetric stretching vibration was observed. On the other hand, a photoelectron spectrum of CO2 molecule at 900K shows a band structure of deformation vibrations. Our results shows hot CO2 molecules are deformed and corresponding Franck-Condon region changes.
