WebIn order to understand the transition mechanism, we measured the temperature dependence of 1H CRAMPS solid state NMR and 13C CP/MAS spectra of D- and L-alanine crystals from 295K through to 220K.Obvious difference of NMR behaviors between two enantiomers was observed in the phase transition process. WebSolid-state 13C magic-angle spinning (MAS) NMR spectroscopy is used to investigate the structure of the Cu(ii)-based metal–organic frameworks (MOFs), HKUST-1 and STAM-1, …
WebThis is attributed to strong interactions with Lewis basic guest molecules. Here we show that a combination of 13C MAS NMR spectroscopy with state-of-the-art density functional theory (DFT) calculations allows one to unravel the interactions of water, 2-aminopyridine, 3-aminopyridine, and diethylamine with the open metal sites in Cr-MIL-101. WebSolid-state NMR spectra were recorded at room temperature in a Varian/Agilent spectrometer operating at the NMR frequencies of 399.73 and 100.52 MHz for 1 H and 13 …
