The very strong H-bond is believed to cause the large absorption observed in acid solutions. In this talk we present theoretical investigations of the vibrational spectrum of this ion. We have calculated a potential surface for all of its 15 degrees of freedom by pointwise ab initio MP2 computations using a large basis set. Analytical expressions of various forms have been fitted to these points, and anharmonic vibrational frequencies have been calculated for parts of this surface using collocation methods. In particular, we suggest where the peak for the hydrogen-bonded OH stretching vibration can be found. en_US dc.format.extent 64371 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title VIBRATIONAL SPECTRA OF THE $H_{5}{O_{2}}^{+}$ COMPLEX FROM THEORETICAL CALCULATIONS en_US dc.type article en_US
