Label the significant peaks in the IR and NMR spectra. When analyzing the signals in the 'HNMR, be sure to include all appropriate information. For example: 3H, singlet, 0 neighbors, and c (the letter referring to the corresponding unique type of hydrogens that were labeled in the structure). It is recommended to provide more analysis for each signal than what is described above, when necessary, such as labeling any coupling constants if any are provided For NMR label each peak...

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).
Your final structure must be consistent with the chemical shift...

Information: Each spectra below was obtained from a pure compound. Mass Spectrum parent peaks (M) are listed for all examples. IR peaks listed are strong (s) unless otherwise indicated for signals above 1500 cm H NMR Spectra, the integral is given in number of hydrogens (#H) or as a relative ratio. Important coupling constants (-values) are listed next to the peaks for some examples. For some spectra, an inset (grey box) is...
