WebHydrogen-1 NMR spectroscopy provides more information about the environments of the nuclei it detects through integration traces and spin-spin coupling. NMR spectroscopy produces unique, well-resolved spectra. It can be used to distinguish between different functional groups and environments in a molecule. WebThe C-13 NMR spectrum for but-3-en-2-one. This is also known as 3-buten-2-one (amongst many other things!) Here is the structure for the compound: You can pick out all the peaks in this compound using the simplified table above. The peak at just under 200 is due to a carbon-oxygen double bond.
