| Outline of Final Research Achievements |
Water cluster anions are a model system of the solvated electron. They have two isomer types; one is the interior type, in which the excess electron is trapped in the cavity of the cluster. Another is the surface type, in which the excess electron is bound on the surface. Though the assignment of the isomer types has been performed by infrared and photoelectron spectroscopies, their conclusions have been inconsistent. In the present study, we carried out infrared spectroscopy of large water clusters which hold a cation on their surface through a single contact water molecule. Their hydrogen bond networks are expected to be similar to those of the surface type water cluster anions. In these clusters, the hydrogen bond networks are strongly polarized to stabilize the cation. We discuss the influence of the water network polarization on the infrared spectra. In addition, we try to extend infrared spectroscopy of water cluster anions to the larger size region.
