STRUCTURE DETERMINATION PROBLEMS USING IR AND PROTON NMR
SPECTROSCOPY
Determine the structure of the six compounds whose IR and PMR
spectra are provided on the attached sheets, given the following
comments about the provided information and spectra.
PMR Spectra: The PMR spectrum of each compound is provided,
along with peak areas. The peak areas are given as the simples
whole number ratio of protons and are indicated (for exmpale, 4H).
