Because of their central importance in chemistry and biology, water molecules have been the subject of decades of intense spectroscopic investigations. Rotational spectroscopy of water vapor has yielded detailed information about the structure and dynamics of isolated water molecules as well as stable water dimers and clusters. Nonlinear rotational spectroscopy in the terahertz regime has been developed recently to investigate rotational dynamics of linear and symmetric-top molecules whose…

Vibrational Spectroscopy and Dynamics of Water.

An overview of recent static and time-resolved vibrational spectroscopic studies of liquid water from ambient conditions to the supercooled state, as well as of crystalline and amorphous ice forms, reveals a coherent picture of water dynamics and energetics.

Nonlinear two-dimensional terahertz photon echo and rotational spectroscopy in the gas phase

Ultrafast 2D terahertz spectroscopy of gas-phase molecular rotors at room temperature enables direct observation of correlated rotational transitions and may reveal rotational coupling and relaxation pathways in the ground electronic and vibrational state.

Water vibrations have strongly mixed intra- and intermolecular character.

These spectra reveal vibrational transitions at all frequencies simultaneous to the excitation, including pronounced cross-peaks to the bend vibration and a continuum of induced absorptions to combination bands that are not present in linear spectra, which provide evidence for strong mixing of inter- and intramolecular vibrations in liquid H2O.

Two-dimensional Raman-terahertz spectroscopy of water

The work extends multidimensional vibrational spectroscopy into the far-IR regime where thermally excited soft modes are found that are directly responsible for molecular dynamics, and can elucidate couplings and inhomogeneities of the various degrees of freedoms.

Coherent two-dimensional terahertz-terahertz-Raman spectroscopy

2D teraherz-terahertz-Raman (2D TTR) spectroscopy is presented, the first technique, to the authors' knowledge, to interrogate a liquid with multiple pulses of terAhertz (THz) light, and control the orientational alignment of molecules in a liquid, and nonlinearly excite vibrational coherences.

Quantum coherence selective 2D Raman–2D electronic spectroscopy

A method that probes correlations between states within the vibrational and electronic manifold with quantum coherence selectivity by combining near-impulsive resonant and non-resonant excitation, and the desired fifth-order signal of a complex organic molecule in solution is measured free of unwanted lower-order contamination.

Ultrafast 2D IR spectroscopy of the excess proton in liquid water

Time-resolved vibrational spectra spanning a broad region of the mid-infrared elucidate how water accommodates the protons in acid and suggest a key role for the Zundel complex in aqueous proton transfer.

An upper limit for water dimer absorption in the 750 nm spectral region and a revised water line list

Abstract. Absorption of solar radiation by water dimer molecules in the Earth's atmosphere has the potential to act as a positive feedback effect for climate change. There seems little doubt from the

Structural relaxation in supercooled water by time-resolved spectroscopy

Time-resolved optical Kerr effect measurements are reported that unambiguously demonstrate that the structural relaxation of liquid and weakly supercooled water follows the behaviour predicted by simple mode-coupling theory, supporting the interpretation of the singularity as a purely dynamical transition.
