The following exercises are designed to help you become familiar with predicting the 1H NMR spectra of simple organic molecules. For each example you should find the number of signals you expect, where they should show on the scale (chemical shift), and what shape they should be (splitting patterns).
16 Δεκ 2021 · As seen in the 1 H NMR spectrum of methyl acetate (Fig. 6.6a), the x-axis units of NMR spectrum are in ppm (not in Hz as we would expect for frequency), and the two signals stand at different position along the x-axis. Let’s explain how that works and what information can be obtained.
Let's summarise what can be obtained from a 1 H NMR spectrum: Chemical shift. The chemical shift is the position on the d scale (in ppm) where the peak occurs. Typical d /ppm values for protons in different chemical environments are shown in the figure below.
