S1) [29]. The molecular structure was characterized using proton nuclear magnetic resonance (1H NMR), carbon-13 nuclear magnetic resonance (13C NMR), and Fourier transform infrared (FTIR) spectra, confirming the successful synthesis of the monomer (Figs. S2–S4). 1H NMR (400 MHz, deuterium ...
29Si NMR spectra of 10 phase samples synthesized from oxide and from crystalline talc starting materials contain a peak near -87 ppm for Q2 Si, in addition to the main peak at -98 ppm for the talc-like Q3 of the tetrahedral sheet. The 1H MAS NMR spectra of the 10 phase contain two ...

This work reports on a new NMR method for studying the kinetics of non-catalyzed sodium borohydride hydrolysis in highly concentrated solutions. The effects of initial NaBH4 concentration, temperature and pH on conversion are studied. It is found that higher initial NaBH4 concentration and higher ...
(NMR) spectroscopy and matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS), and the corresponding1H NMR spectra,13C NMR spectra and mass spectra are shown in Supplementary Figs.4–35. The four SMAs exhibit good solubility in non-halogenated solvento-xylene...
Such an ionic complexation was supported by the 1H NMR spectral comparison among PDMAEA-Q, PMAA, and PDMAEA-Q/PMAA dissolved in D2O, in which all the complexation-related 1H resonances of PDMAEA-Q shifted to higher fields (Fig. 2h). The almost no chemical shift of the α-methyl groups...

The structures of the polymers named CPP-g-PEI were characterized by Fourier transform infrared (FT-IR) spectroscopy, elemental analysis (EA), 13C solid-state NMR (13C NMR), thermogravimetric analysis (TG), scanning electron microscopy (SEM), transmission electron microscope (TEM), powder X-...
Since the early 1950s the nuclear magnetic resonance (NMR) spectroscopy has been applied to hydrogen-bonded systems. This technique is, however, utilized less often than the infrared spectroscopy due to complexity of the spectra. In the 1960s the microwave spectra in gas phase for some fairly ...
