I have most of the information, but I need help to organize it based on the prompts below the pictures.
Mass Spec
Molecular Weight:
Important Fragments; what are they and what do they mean? (base peak structure, is there a halogen, is there a benzene ring, is there an odd number of nitrogens, other important fragments that tell something about the structure)
IR
Is there an OH? Wavenumber?
Is there a carbonyl group? If so what type (acid. ester, amide, aldehyde, ketone etc.)? Wave number?
Other important peaks (terminal alkyne, cyano group, aromatic, alkene, nitro group, amine etc.) and where are they?
1H-NMR
Identify every signal; chemical shift, what is it due to( i.e what type of proton, aromatic, aldehydic, O-H, N-H, vinyl etc.) and how many protons does it represent.
13C-NMR
How many different types of carbons are present?
What type of carbon does each signal represent?
How can you put the skeleton together?
LOGIC:
Carefully, and thoroughly show how you used the spectral data to determine your structure. Show how all your data confirms your structure. Especially useful is using 1H-NMR as confirmation.

Organic Chemistry - Using the following IR anaylsis identify the
major peaks and possible functional group identity. Using the two
NMR spectra, discuss the integration of peaks, chemical shifts, and
splitting. Using the mass spectra, identify molecular weight and
important fragments to confirm the structure. Draw the fragments
that correspond to each peak in the mass spectra. Draw the
structure of the unknown that corresponds to all available data.

I have an proton NMR for a compound that I believe to be Salicylic Acid. It has major peaks at 11.0 ppm as well as around 10.5 ppm. Both peaks are broad singlets indicating that they should be -OH peaks. However, the typical Phenol has a peak around 5-6 ppm. Could it be possible that the aromatic ring and carbonyl group from the carboxylic acid influenced the phenol group enough to shift it that far downfield?
