Analyze the spectrum below and using the integrations and
chemical shifts, assign the protons for the structure shown.
Analyze the spectrum below and using the integrations and chemical shifts, assign the protons for the structure shown. If any of the four labels are incorrect, you will see a red X on the top left corner of the spectra. The doublet at 4.1 ppm, upon expansion, shows a doublet of triplets. Explain this extra splitting. The doublet at 4.1 ppm is...
Q2 - Predict the chemical shifts for the circled protons in the 'H NMR spectrum of each of the following compounds. Write a numerical value or approximate range in ppm.
For chemical shifts of the protons labeled x, y, &z which is the correct order from height to lowest effective field(ie., deshielded > sheilded) in the H NMR spectrum?
3. Predict the 1H NMR spectrum of the molecule shown to the left. Be sure to include the x-axis for the 'H NMR spectrum labelled with units, peaks for each of the non-equivalent protons clearly showing the expected splitting patterns, approximate chemical shifts, and integration
draw the compound and assign the peaks to it

2. Determine and sketch the spectrum, the Fourier transform, of x() where -2l +cos(0)+ jsin for -<t<
For chemical shifts of the protons labeled x, y,& z, which
is the correct order from highest to lowest effective field (i.e.,
deshielded shielded) in the 1 H NMR spectrum?
note: the 1 before the H is suppose to be a superscript
For chemical shifts of the protons labeled x, y, & z, which is the correct order from highest to lowest effective field (i.e., deshielded > shielded) in the 1H NMR spectrum? x > y > z x > z > y y > x > z y > z > x z > x > y z > y > x
sketch the 1H NMR spectrum for the following compounds; label
the peaks with corresponding protons and include the relative
integration numbers for each signal.
(if you could do both, that would be great. i dont think i did
the top one right. Thank you!)
