Liquid Water: When Hyperpolarizability Fluctuations Boost and Reshape the Second Harmonic Scattering Intensities

Autor: Guillaume Le Breton, Oriane Bonhomme, Emmanuel Benichou, Claire Loison

Publikováno v: The Journal of Physical Chemistry Letters. 14:4158-4163

Second Harmonic Scattering (SHS) is a method of choice to investigate the molecular structure of liquids. While a clear interpretation of SHS intensity exists for diluted solutions of dyes, the scattering due to solvents remains difficult to interpre

First hyperpolarizability of water in bulk liquid phase: long-range electrostatic effects included via the second hyperpolarizability

Autor: Claire Loison, Guillaume Le Breton, Oriane Bonhomme, Emmanuel Benichou

Publikováno v: Physical Chemistry Chemical Physics. 24:19463-19472

The molecular first hyperpolarizability β contributes to second-order optical non-linear signals collected from molecular liquids. The second hyperpolarizability γ permits to model how the environment far away from a target molecule impacts its β.

The molecular first hyperpolarizability β contributes to second-order optical non-linear signals collected from molecular liquids. For the Second Harmonic Generation (SHG) response, the first hyperpolarizability β (2ω,ω,ω) often depends on the m

Amide I difference spectroscopy is widely used to investigate protein function and structure changes. In this article, we show that the common approach of assigning features in amide I difference signals to distinct secondary structure elements in ma

Molecular dynamics simulations of aqueous electrolytes generally rely on empirical force fields, combining dispersion interactions - described by a truncated Lennard-Jones (LJ) potential - and electrostatic interactions - described by a Coulomb poten
