1H NMR spectrum A corresponds to a molecule with the formula C3H5Cl.
1H NMR spectrum A corresponds to a molecule with the formula C3H5Cl. The compound shows significant IR bands at 730 (see Problem 53 of Chapter 11), 930, 980, 1630, and 3090 cm-1.
(a) Deduce the structure of the molecule.
(b) Assign each NMR signal to a hydrogen or group of hydrogens.
(c) The “doublet” at δ = 4.05 ppm has J ≈ 6 Hz. Is this in accord with your assignment in (b)?
(d) This “doublet,” upon five-fold expansion, becomes...

How do the spectra of the metal salts differ from each
other and from the spectrum of the hydrogen
atom? Be specific, referring to observations
made on your spectra. Include the shapes and numbers of the lines
you observe.
Why do the spectra of the metal salts differ from the
spectrum of the hydrogen atom? Be specific,
connecting your observations made on your spectra from the
different salts and the hydrogen atoms as they relate to the
theory.

In H2O, the 31P NMR spectrum of the compound gives 2 lines
shifted from each other by about 1ppm, corresponding to the hydrate
and ketone in the ratio of 60:40.
You want to measure the rates of interconversion between them in
the range of 0.1-3.0 per second using a cross relaxation method.
Both the hydrate and ketone have T1's of 5.0 second and linewidths,
delta v1/2 of 2 hz. The experiments are performed in a field such
that the 31P...
