Nuclear magnetic resonance (NMR)
spectroscopy can be used to gather information about the structure
of a compound. The chemical shift of peaks in a 1H NMR or a 13C NMR
spectrum can be used to gather information about the types of
neighboring functional groups. The spin-spin splitting pattern in a
1H NMR spectrum can be used to determine the number of hydrogen
atoms on neighboring carbon atoms.
The chemical shift (?) of an atom is influenced by the
electrons...

FTIR and NMR Spectra After completing a reaction and working up the products, it is still necessary to confirm that the correct product was formed. The most common tools used for this analysis are Fourier Transform Infrared (FTIR) and Nuclear Magnetic Resonance (NMR) spectroscopy. In the virtual laboratory, 'H and C NMR spectra are available. Details on interpreting FTIR and NMR spectra are found in your textbook. Your instructor may or may not...

For the determination of the structural formula of aromatic
compound A, the 1 H-NMR spectrum was obtained, which is given
below.
Compound A was subjected to the five (5) stage experiment,
which follows. It is stated that in Stage I the yield was 45%,
while for the remaining stages the yield was 100%.
Step I: Amount of 0.02 mol of Compound A after treatment with
concentrate NaOH under the appropriate conditions, gave the organic
products B and C.
