The SiH3OH2+ ion is generated in a silane/water plasma expansion, and its structure is derived from the IR photodissociation (IRPD) spectrum of its Ar cluster measured in a tandem mass spectrometer. The chemical bonding in SiH3OH2+ is analyzed by density functional theory (DFT) calculations,...
In this work, we perform Fourier transform IR spectroscopy experiments of liquid light, semi-heavy, and heavy water; we analyze the data obtained with a model of the dynamical structure of liquid water, to elucidate the elusive ionic contributions to its IR spectrum. In comparison with previous...
The buffer solutions were prepared with the use of boric acid (H3BO3; 99.6%, ACS grade, Acros), phosphate dipotassium phosphate (K2HPO4; ACS grade, Spectrum Chemical) and monopotassium phosphate (KH2PO4; analytic grade, Merck). Sodium dichromate dihydrate (Na2Cr2O7·2H2O; ACS grade, Merck) ...

rotational lines of H2O, HDO, and H218O. Changes in the steady state power are tied to intracavity losses due to molecular absorption, and the resulting spectrum yields nearly simultaneous measurements of the number density of the absorbing gases within the cell, much as in traditional IR absorp...
In Persian: “Dabir.” In the Sasanian and early Islamic period, the term “Dehqân” was used for minor landowners directly involved in agriculture, who was the manager of local affairs on the village scale, and whom peasants were forced to obey. Later, the term “Kadkhoda” replaced ...
Infrared predissociation spectra of water clusters have been measured in the frequency range 3000–3800 cm1using a molecular beam–color center laser appar... DF Coker,RE Miller,RO Watts - 《Journal of Chemical Physics》 被引量: 516发表: 1985年 The Water Vapor Spectrum in the Region 8600–...
Water monitoring technologies are widely used for contaminants detection in wide variety of water ecology applications such as water treatment plant and water distribution system. A tremendous amount of research has been conducted over the past decades to develop robust and efficient techniques of contami...
21 showed that the IR spectrum of gaseous CO2 consists of two branches with fine lines at 2300–2380 cm−1, while dissolved CO2 in water exhibits a single peak at about 2340 cm−1. Similarly, Zhang et al.22 demonstrated experimentally that a very thin gas domain (i.e., surface ...
