Miquel Garcia-Ratés, Pere Miró, Josep Maria Poblet, Carles Bo, and Josep Bonet Avalos . I actually have an ATR IR Spec, which is (supposedly) meant for reading aqueous solutions... ...but it doesn't really work... it can't be used for figuring out dilutions (well maybe, give or take 20%). †Part of the special section “Aqueous Solutions and Their Interfaces”. S Water film confined in a nanoscale gap: Surface polarity and hydration effects. T. Anh Pham, P. Huang, E. Schwegler, and G.

The actual total number of the first order water-related bands is no less than 15, thus being several times greater than that assumed earlier. molecular dynamics study of water at constant pressure using converged basis sets and empirical dispersion corrections. We compare calculations of infrared (IR) spectra of water confined between nonpolar surfaces, obtained by molecular dynamics simulations with forces either computed using density functional theory or modeled by empirical potentials. Water shows strong and broad absorbance band in IR spectrum, around 3200-3600 (aym and sym O-H str. The … the Altmetric Attention Score and how the score is calculated.

ScienceDirect ® is a registered trademark of Elsevier B.V. Water-related bands in the IR absorption spectra of silicate glasses. Comparison of the interfacial dynamics of water sandwiched between static and free-standing fully flexible graphene sheets. The absorbance around 3430 is not broad like an OH peak is, that's why I was thinking perhaps it was a water impurity in my sample. 2 Zhonghua Ma, Yanli Zhang, Mark E. Tuckerman. In the 1500–3700 cm−1 region, the spectra are shown to contain 14–15 bands. Theoretical Investigation of Solvent Effects and Complex Systems: Toward the calculations of bioinorganic systems from ab initio molecular dynamics simulations and static quantum chemistry. Heather J. Kulik, Eric Schwegler, and Giulia Galli . The water-related first-order IR spectra of binary and more complex silicate glasses occupy the broad 1500–3700 cm −1 region, thus extending far outside the low-wavenumber limit of 2300 cm −1 assumed in the commonly acknowledged approaches.

Also water makes the KBr disc very opaque which will reduce the absorption of the IR by the samples. Four bands located within the 2850–3400 cm−1 region are confirmed to be due to the components of the asymmetric and symmetric stretching modes of the H2O molecule.
