Based on Raman spectra of light, heavy, and half-heavy water in the region of O-H and O-D stretching vibrations and on the independent-oscillator model, it is shown that a peculiarity of the liquid state of water is the nonequivalence of O-H groups of water molecules in hydrogen bonding. The structure of liquid water and the mechanism of its molecular mobility are considered in this context. 相似文献

Anhydrous lanthanum nitrate and its complexes with one and two ethylenediamine molecules are calculated by the ab initio B3LYP/LANL2DZ quantum-chemical method. An ethylenediamine molecule is shown to coordinate preferentially through one amino group, and a hydrogen bond is formed between the coordinated amino and nitrato groups. An ethylenediamine complex of lanthanum nitrate is synthesized, and its composition and thermal stability are determined. The IR spectra of the ethylenediamine complex of lanthanum nitrate confirm the presence of the intramolecular hydrogen bond in this complex. 相似文献

Conclusions The IR spectra of methyl- and phenylchloromenthoxysilanes, menthoxypropylalkylehlorosilanes, menthoxypropyl- and menthoxyethylmethylethoxysilanes, and also chlorosilylpropionic and chlorosilylisobutyric acid menthyl esters were studied. Assignments of the frequencies for a number of vibrations were made.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 9, pp. 2151–2155, September, 1968. 相似文献

Identification of peroxo groups in supramolecular layered structures as probed by Raman spectroscopy
T. A. Tripol’skaya I. V. Pokhabova P. V. Prikhodchenko G. P. Pilipenko E. A. Legurova N. A. Chumaevskii 《Russian Journal of Inorganic Chemistry》2009,54(3):464-466
Peroxide-containing supramolecular structures prepared by reacting lithium aluminum layered double hydroxides (Li-Al LDHs)
with concentrated hydrogen peroxide solutions were characterized by Raman spectroscopy. These compounds were formulated as
[LiAl2(OH)6](OH) · H2O2 · H2O(I) and [LiAl2(OH)6](OOH) · H2O2 · H2O(II). The frequencies 830 and 849 cm−1 in the spectra of compounds I and II were assigned to O—C stretching vibrations in two nonequivalent peroxo groups. The band
at 866 cm−1 in compound II was assigned to O—O vibrations in the hydroperoxo group (OOH)−. Proceeding from calculated strength factors, we inferred that the O—O bond in the hydroperoxo group of compound II is stronger
than in the H2O2 solvating group.

Reaction of o-dichlorobenzene with dimethylmethoxychlorosilane and sodium leads to the isolation of dimethyl(o-chlorophenyl) methoxysilane, o-bis(bimethylmethoxysilyl)benzene, 1,1,3,3-tetramethyl-1,3-disila-2-oxaindane, and 1, 1-dimethyl-1-silarribenzocycloheptatriene. When I is polymerized with H2SO4, the phenyl group is observed to split off. 相似文献
