Discuss the differences observed in the IR and NMR spectra of
(E)-cinnamic acid and 2,3-dibromo-3-phenylpropanoic acid that are
consistent with addition of bromine to the double bond.
There are several distinct differences between IR and UV-Vis
spectroscopy. Discuss the following as they relate to:
(a) The types of interactions responsible for the
signals generated
(b) Source of radiant energy
(c) Signal detection
(d) Sample cells
(e) Sample preparation
List three changes you would expect in the IR spectrum of
2,3-dibromocinnamic acid as compared to the IR spectrum of
trans-cinnamic acid. Make sure to reference the approximate
wavenumber of any relevant peaks and whether they correspond to a
stretch or a bend.

from an analysis of IR spectrum of dimedone , is it possible to
determine the keto/enol ratio? How can one do this ? Describe two
other methods to distinguish between the keto-and enol-forms in
organic chemistry.
