Outline of Final Research Achievements

The apparatus of PDN-CRDS has been improved to observe electronic transitions of the radical-molecular complexes. We tried to observe electronic transitions of their prototypical species of the Ar-CN complex. Although the intensity of the strongest absorption of the CN monomer was improved to 180 ppm/pass, absorptions of the complex were not observed. Absorptions of water complex, H2O-CN were also searched under similar experimental conditions and weak broad absorptions were observed. The spectral carrier has not been confirmed so far due to their intensities and the wavelength resolution of the utilized laser.
The ground state and first excited electronic state of HO3 were studied. The re structure of ground state HO3 was determined using experimental rotational constants and theoretical rotation-vibration constants. The molecular structure of HO3 in the first excited electronic state was found to be similar to closed-shell species HO3H.
