dc.description.abstractThe fundamental transition DELTAG01 and the higher transitions DELTAG02 and DELTAG03 are investigated in their polarization and temperature dependence. The spectral position of the transitions follows closely a Morse potential with D(e) = 4.75 eV and the mechanical anharmonicity omega(e)x(e) = 88.5 cm-1 leaving no room for speculations about possible hydrogen bonding. The intensity ratio of higher vibrational transitions indicates a strong temperature dependence of the electrical anharmonicity. An absorption side band at 4436 cm-1 which follows in intensity the absorption of the DELTAG01 transition (and therefore the OH concentration), is identified as a vibrational librational combination side band. Its polarization displays a 3-dimensional behaviour with an intensity ratio I perpendicular-to/I parallel-to almost-equal-to 2 with respect to the z over arrow pointing right-direction. The librational frequency is an important input parameter for the discussion of the protonic conductivity.
