(Hen)2(L)3](PW9O34)2[Ni(H2O)5]}·20H2O (1, en = 1,2-ethylenediamine, L = iminodiacetate), has been made under hydrothermal conditions and characterized by IR spectrum, thermogravimetric analysis, elemental analysis, single-crystal X-ray diffraction and powder X-ray diffraction, ...
modes of the cage-surface-bound H3O+near 2600 cm−1, which were not evident at all in the experimental spectrum1. Later, Torrent-Sucarrat and Anglada30have shown that the anharmonic coupling plays a crucial role in the characterization of the IR spectrum of the H+(H2O)21cluster. Their...
plane, along with minor peaks at 12.4°, 18.8°, 20.4°, and 25.3° that are attributed to the (220), (330), (502), and (440) crystal planes, respectively (Fig.1c). To elucidate the crystal structure of MCOF-Ti6Cu3, the staggered stacking model in theR3andP63space groups correspon...
One representative IR spectrum of the omphacite is given in Fig.4c and displays two bands between 3400 and 3550 cm−1with the strongest absorption at 3460 cm−1. Occasionally, omphacite has a third band at 3630 cm−1(e.g., Skogby2006), which is almost negligible to absent in the ...
Tentative assignments are given for the observed peaks, and it is concluded that the acids adsorb as formate and acetate ions on the surface. Tunneling spectra for several submonolayer coverages of HCOOH ( θ = 0.03, 0.08, 0.3 and 0.4) have been measured in addition to the spectrum ...
Infrared Action Spectra of Ca2+(H2O)1169 Exhibit Spectral Signatures for Condensed-Phase Structures with Increasing Cluster Size Infrared laser action spectroscopy is used to characterize divalent calcium ions solvated by up to 69 water molecules. The spectrum for Ca2+(H2O)12 indicat... Matthew,F....
On the other hand, the OH maser spectrum shows double peaks with a velocity separation of ~25 km/s (V_LSR=$111--116 and 138--141 km/s), as typically seen in circumstellar envelopes of OH/IR stars. The angular offset between the velocity-integrated brightness peaks of the two high-...
It must be noted that the wavenumber of any particular absorption phenomenon in the IR spectrum also changes in relation to the measuring technique (Fig. 5, Fig. 6, Table 4) and so do the respective linear regression coefficients (Table 4). The shift in band position between different measur...
The newly obtained Raman spectrum shows peaks at 312.7, 374.3 and 656.8 cm−1, which match the bulk Mn2O317. Similar Raman spectral profiles and behaviors were also observed for the Na0.55Mn2O4·1.5H2O sample (Supporting Information, Fig. S15, S16 and S17). Figure 7 Raman spectra ...
