“…In a HDO:D 2 O water bridge, for instance, the lifetime of the local OH stretch vibration of HDO molecules was found to be shorter than in the bulk, while its delocalization by thermalized relaxation lasted longer. 259 The core of the bridge contains water with H þ ions and ice-like features, while the outer shell contains more OHions. 260 In the bridge, a higher H þ mobility than in bulk water has been measured, explained with a stronger hydrogen bond and therefore stronger intermolecular proton delocalization.…”

The interaction of plasma with liquids has led to various established industrial implementations as well as promising applications, including high-voltage switching, chemical analysis, nanomaterial synthesis, and plasma medicine. Along with these numerous accomplishments, the physics of plasma in liquid or in contact with a liquid surface has emerged as a bipartite research field, for which we introduce here the term "plasma physics of liquids." Despite the intensive research investments during the recent decennia, this field is plagued by some controversies and gaps in knowledge, which might restrict further progress. The main difficulties in understanding revolve around the basic mechanisms of plasma initiation in the liquid phase and the electrical interactions at a plasma-liquid interface, which require an interdisciplinary approach. This review aims to provide the wide applied physics community with a general overview of the field, as well as the opportunities for interdisciplinary research on topics, such as nanobubbles and the floating water bridge, and involving the research domains of amorphous semiconductors, solid state physics, thermodynamics, material science, analytical chemistry, electrochemistry, and molecular dynamics simulations. In addition, we provoke awareness of experts in the field on yet underappreciated question marks. Accordingly, a strategy for future experimental and simulation work is proposed.

“…Accordingly, such ion-molecule interactions have been extensively studied by FTIR experiments and theoretical methods for a few decades [1][2][3][4][5][6][7]. However, the effect of ions on vibrational dynamics of a given molecule has begun to be investigated recently with an advent of time-resolved vibrational spectroscopic techniques such as ultrafast infrared-Raman, infrared pump-probe (IR PP), and two-dimensional IR (2DIR) experiments [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. A vibrationally excited molecule undergoes different relaxation processes on various timescales including vibrational energy transfer to anharmonically coupled vibrational modes [23,24], vibrational energy dissipation into the solvent [25], and resonance energy transfer to nearby vibrational modes with similar vibrational energies [26][27][28][29][30].…”

“…The key observations in water bridges that motivated this study were: Density gradients (7% edge to core) observed using optical techniques (6), anisotropy observed in neutron scattering (9), optical birefringence from polarized light scattering (11,12) and changes in the OH stretch vibration from Raman and infrared measurements (10,13).…”

The floating water bridge phenomenon is a freestanding ropeshaped connection of pure liquid water, formed under the influence of a high potential difference (approximately 15 kV). Several recent spectroscopic, optical, and neutron scattering studies have suggested that the origin of the bridge is associated with the formation of anisotropic chains of water molecules in the liquid. In this work, high energy X-ray diffraction experiments have been performed on a series of floating water bridges as a function of applied voltage, bridge length, and position within the bridge. The two-dimensional X-ray scattering data showed no directiondependence, indicating that the bulk water molecules do not exhibit any significant preferred orientation along the electric field. The only structural changes observed were those due to heating, and these effects were found to be the same as for bulk water. These X-ray scattering measurements are supported by molecular dynamics (MD) simulations which were performed under electric fields of 10 6 V∕m and 10 9 V∕m. Directional structure factor calculations were made from these simulations parallel and perpendicular to the E-field. The 10 6 V∕m model showed no significant directional-dependence (anisotropy) in the structure factors. The 10 9 V∕m model however, contained molecules aligned by the E-field, and had significant structural anisotropy.water electric field | pair distribution function | temperature dependence | high voltage
