Raman spectroscopy crystallinity
WebbRaman spectra of syndiotactic polypropylenes of different stereoregularity are reported. Spectra for ordered and disordered structures of these polymers were simulated using a small number of parameters. The features that occur in the 300 and 400 cm -1 regions can be used to assess chain tacticity. A quantitative determination of the racemic content of … WebbWe assess the binding of C 2 H 4 to the coordinately unsaturated copper(I) sites of the metal–organic frameworks Cu(I)-ZrTpmC* and Cu(I)-MFU-4l via 13 C solid-state nuclear magnetic resonance spectroscopy, density functional theory (DFT), and natural localized molecular orbital analysis. Using these methods, forward-donation and back-donation …

WebbSolid state Raman spectroscopy revealed two crystalline phases: chalcopyrite and the so-called copper−gold phase, and by increasing the annealing temperature of the particles, the formation of the chalcopyrite phase is favored. UV−visible measurements showed that the n-type CuInS2 possesses a direct bandgap energy of 1.55 eV.
Webb12 apr. 2024 · Figure 2 shows the Raman spectra of the Cu(en) crystal in the frequency range 0–3500 cm –1 at room temperature (lower spectrum). No Raman lines were detected in the frequency range above 3500 cm –1. As can be seen from the figure, the spectrum lines are quite intense. Webb8 maj 2024 · Introduction. Raman spectroscopy is a characterization technique that detects bond vibrations that change the polarizability of the molecule. It is therefore a non-destructive technique and is suitable for examining both polymers and their additives. In general, Raman spectra can be used for identification purposes by referring to a …
