The 14N NMR spectrum was challenging to obtain because of the low Larmor frequency (28.90 MHz). The chemical shifts in the 14N NMR spectra at various temperatures are shown in Fig. 7. The structural geometries of N(1) and N(2) in the two [NH2(CH3)2]+ groups were determined based ...

The crystal structure of UiO-66-NH /GO/Fe O is good, and the diffraction peaks of UiO- 2 3 4 66-NH /GO and Fe O exist simultaneously in the XRD spectrum. The FT-IR spectrum shows a 2 3 4 strong Fe-O-Fe typical absorption peak near 580 cm-1, and the characteristic peak of ...
Fig. 2. FT-IR spectra of NH2-MIL-53(Al) andl-Cysteine–NH2–MIL-53(Al). The XRD spectrum was shown inFig. 3. By analyzing the XRD spectrum of NH2-MIL-53(Al), it was consistent with the characteristic peaks of the XRD spectrum of the same material in other references. It indicate...
sites, as delineated within the framework of the Freundlich isotherm, manifests as a spectrum of varying binding energies, rather than a uniform energy distribution. This distribution adheres to an exponential-type function, closely approximating the complexities of actual adsorption scenarios74(Eq.4)...

Ab initio molecular electronic structure theory has been employed in order to investigate systematically the X 3B1, 1A1, b 1B1, and c 1Σg+ states of NH2+, with emphasis placed on the b 1B1 and c 1Σg+ states. The self-consistent-field (SCF), configuration interaction with single a...
