The 13 C NMR spectrum for but-3-en-2-one. This is also known as 3-buten-2-one (among 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 ppm is due to a carbon-oxygen double bond.

So the peak corresponding to 1.0 ppm is due to methyl protons. That’s about the easy way of interlinking the concept to remember NMR spectrum table with both logic and reasoning. 2013-06-11 · Error2 (ppm) = 0.001 Da * 1,000,000 / 600.0000 = 1.7 = 2 ppm The conversion for the NMR shifts from Hz to PPM is: Sample shift (ppm) = ( F(sample in Hz) – F(reference in Hz) ) / F(spectrometer in Hz) * 1,000,000 Sample Shift1 (ppm) = ( 1500.00 Hz – 0.00 Hz ) / 500 Hz = 3.00 ppm Sample Shift2 (ppm) = ( 3000.00 Hz – 0.00 Hz ) / 500 Hz = 6 NMR Appendix.

Conversely, 1 ppm on a 200 MHz NMR spectrometer corresponds to: 1 x 10-6 x 200 x 106 Hz = 200 Hz and 1 ppm on a 400 MHz NMR spectrometer corresponds to: 1 x 10-6 x 400 x 106 Hz = 400 Hz This ppm scale relative to TMS and the increasing value to the lower magnetic field (i.e., to the left from TMS) is called “the δ-scale.”
