2-Butanone Compound with spectra: 127 NMR, 19 FTIR, 3 Raman, 44 MS (GC), and 2 Near IR

2023年2月11日 · Butan-2-one shows a chemical shift around 2.1 on a 300 MHz spectrometer in the H 1 NMR spectrum. a) How far downfield is this peak from TMS in Hz? b) If the spectrum was done with a 400 MHz instrument, would a different chemical shift be seen?

For relatively simple molecules, the low resolution H-1 NMR spectrum of butanone is a good starting point. The hydrogen atoms (protons) of butanone occupy 3 different chemical environments so that the H-1 proton low resolution NMR spectra should show 3 peaks (diagram above for butanone).

Before you look at the NMR spectrum, think about what the spectrum of 2-butanone should look like. There are three different types of protons: The 3 protons in green will be a singlet and show up from 2-2.7 ppm. The 2 protons in blue will be split to a quartet by the protons in red; they will show up from 2-2.7 ppm.

What do the number and values of the chemical shifts from the c-13 carbon-13 NMR spectrum tell us about the butanone molecule? explaining the decoupled carbon-13 NMR spectrum of butanone with a detailed interpretation diagram of all the C-13 chemical shifts and intensities

Butanone has 4 carbon atoms, so on average, ~1 in 25 molecules will contain a 13C atom. The most abundant (most intense, tallest) ion peak of the molecule under mass spectrometry investigation (butanone) is usually given an arbitrary abundance value of 100, called the base ion peak, and all other abundances ('intensities') are measured against it.
