TL;DR: Changes in the spectra of tetrahydrofuran hydrate with temperatures close to the hydrate's dissociation temperature were observed and may be connected to changes inHydrate's local structure due to the formation of hydrogen bonds between guest and water molecules.
Abstract: We report on the formation of tetrahydrofuran clathrate hydrate studied by x-ray Raman scattering measurements at the oxygen K edge. A comparison of x-ray Raman spectra measured from water-tetrahydrofuran mixtures and tetrahydrofuran hydrate at different temperatures supports stochastic hydrate formation models rather than models assuming hydrate precursors. This is confirmed by molecular dynamics simulations and density functional theory calculations of x-ray Raman spectra. In addition, changes in the spectra of tetrahydrofuran hydrate with temperatures close to the hydrate's dissociation temperature were observed and may be connected to changes in hydrate's local structure due to the formation of hydrogen bonds between guest and water molecules.

TL;DR: In this article, the extent of intramolecular hydrogen-bonding, as determined by infra-red spectroscopy in the hydroxyl stretching region, in certain vicinal diols of cyclo hexane, cyclo pentane, tetrahydropyran, and in related compounds provides evidence for the stabilities of different conformations.

TL;DR: The thermal decomposition of compounds of the type Cp 2 TiR 2 (Cp = cyclopentadienyl, R = aryl or benzyl) in the solid state and in various solvents has been studied.

TL;DR: Polyaniline, a polymer widely known to be poorly soluble in a wide range of solvents has been successfully fabricated into an asymmetric membrane and stabilised by thermally induced cross-linking to result in a THF stable pervaporation membrane tested over 40h as mentioned in this paper.

TL;DR: In this paper, the structure of Ru2(O2CMe)4L2(L = H2O or thf) and Ru2O2CEt)4(Me2CO)2 have been determined by X-ray crystallography and the well known D4h symmetry of binuclear tetracarboxylates established.
Abstract: The interaction of the reduced ‘blue solutions’ of ruthenium chloride in methanol with alkali-metal carboxylates yields the air-sensitive paramagnetic complexes, Ru2(µ-O2CR)4(R = H, Me, CH2Cl, Et, or Ph), that form weakly end-co-ordinated bis adducts, Ru2(µ-O2CR)4L2[L = H2O, MeOH, tetrahydrofuran (thf), Me2CO, or MeCN]. Electrochemical measurements, electronic and i.r. absorption spectra, and magnetic susceptibility data are given. The structures of Ru2(O2CMe)4L2(L = H2O or thf) and Ru2(O2CEt)4(Me2CO)2 have been determined by X-ray crystallography and the well known D4h symmetry of binuclear tetracarboxylates established. The Ru2(O2CR)4 core shows a constant geometry with Ru–Ru = 2.261 ± 0.001 A. The three axial donor ligands show slightly varying Ru ⋯ O distances of 2.335(4), 2.363(5), and 2.391(5)A for water, acetone, and thf respectively.
