چکیده

Vibration–rotation–tunneling ~VRT! spectroscopy has been extended to the 4 THz spectral region through the observation of a second intermolecular vibration of (D2O)4 . Analysis of the precisely measured perpendicular transition confirms the previously reported cyclic homodromic structure and reveals a dramatically increased ~303! hydrogen bond rearrangement rate in the excited state. © 1999 American Institute of Physics. @S0021-9606~99!00441-9#

Bifurcation tunneling dynamics in the water trimer

Recent far-infrared vibration–rotation–tunneling experiments have probed intricate details of the hydrogen bond tunneling dynamics in the water trimer through excitation of intermolecular vibrational transitions to states of sequentially increasing energy. The experimentally observed bifurcation splitting in the water trimer evolves from an equally spaced quartet in the vibrational ground state...

Terahertz vibration–rotation–tunneling spectroscopy of water clusters in the translational band region of liquid water

We report the first direct observation of the hydrogen-bond stretching vibration for a water cluster. A perpendicular band of ~D2O!3 was measured by terahertz laser vibration–rotation–tunneling spectroscopy at 142.8 cm in the ‘‘translational band’’ region of the liquid corresponding to the hindered translational motions of water molecules. We have tentatively assigned the spectrum to transition...

Far-infrared VRT spectroscopy of two water trimer isotopomers: vibrationally averaged structures and rearrangement dynamics.

We report the measurement of far-infrared vibration-rotation tunnelling parallel bands of two partially deuterated water trimer isotopomers: (D2O)2DOH and (H2O)2DOH at 97.2607 cm-1 and approximately 86 cm-1, respectively. The hydrogen bond rearrangement dynamics of the two mixed trimers can be described by the simplified molecular symmetry G8, which accounts for both the flipping and bifurcati...

Terahertz Laser Vibration-Rotation Tunneling Spectroscopy of the Water Tetramer

A vibration-rotation-tunneling (VRT) spectrum of (H2O)4 has been recorded near 2.04 THz (67.9 cm-1). The band origin of this ∆K ) 0 symmetric rotor spectrum is shifted by 0.1 cm-1 to the blue of that of a (D2O)4 band reported previously [Science, 1996, 271, 59]. Similar to that spectrum, each transition in the (H2O)4 spectrum exhibits a regular doublet splitting. The (D2O)4 and (H2O)4 doublet s...

Selective probing of the OH or OD stretch vibration in liquid water using resonant inelastic soft-x-ray scattering.

High-resolution O 1s resonant inelastic x-ray scattering spectra of liquid H2O, D2O, and HDO, obtained by excitation near the preedge resonance show, in the elastic line region, well-separated multiple vibrational structures corresponding to the internal OH stretch vibration in the ground state of water. The energy of the first-order vibrational excitation is strongly blueshifted with respect t...
