What is the normal chemical shift range in H NMR spectroscopy?
Chemical shifts in 1H NMR are usually measured relative to tetramethyl silane (TMS), (CH3)4Si, the chemical shift of which is set to 0 ppm. Some organometallic compounds can exhibit upfield chemical shifts in excess of -10 ppm, but most familiar organic compounds have downfield chemical shifts between 0 and 10 ppm. For example, the chemical shift of benzene is 7.26 ppm. The link below has a lot of useful data, covering the whole of the observed range of chemical shifts.
