WebIn addition, when a huge signal generated from water or non-deuterated functional group (e.g., non-deuterated methyl group of acetone-d6) in the deuterated solvent is observed, optimal sensitivity settings (adjustment of receiver gain) in NMR measurement affects the dynamic range, and as a result, the sensitivity of the target signals (i.e ... WebThe NMR spectra were recorded in deuterated chloroform using TMS as internal standard. Chemical shifts are given in parts per million (δ scale) and the coupling constants are given in Hertz. The 1 H NMR spectrum of 7 confirmed the presence of eight proton signals (2.18, 4.01, 4.68, 5.19, 5.3, 5.85, and 6.02 ppm) (Fig. 3.7).The strong signal at 7.2 ppm was …
