The peaks at 2.1 and 0.9 ppm as a CH 2 CH 3 unit. Using the chemical shift charts, the H can be assigned to the peaks as below: 7.2ppm (5H) = Ar H 4.4ppm (2H) = C H2 O 2.8ppm (2H) = Ar-C H2 2.1ppm (2H) = O=CC H2 CH 3 and 0.9ppm (3H) = CH 2 C H3

Web*HOD Peaks - NMR spectra of “neat” deuterated solvent always exhibit a peak due to H 20 in addition to the residual solvent peak. When the exchange rate between H 0 and HDO is slow on the NMR timescale the water peak appears as two peaks, a singlet corresponding to H 20 and a 1:1:1 triplet corresponding to HDO. WebOggi · Fig. 5 illustrates the 1 H NMR spectra for hydrogen gas adsorbed in the 0–7 numbered materials. It should be clarified that none of the sorbents showed significative NMR peaks before exposure to H 2 gas (see Fig. S1 of Supporting Information). De facto, each peak only originates from H 2 filling the material pores. cooking pork loin in oven bag
