Hello,

I have been trying to figure out what the compound indicated by the following spectral data is.

I do believe there is an aromatic, that the molecular weight is 152, and that there is a carboxylic acid or a derivative. 

Any help would be greatly appreciated.

What does the signal in the ¹H-NMR represent?

Start by creating a MF from the NMRs. If no symmetry, 13C-NMR can give a signal for each carbon. 1H-NMR should confirm and give number of hydrogen atoms. In this case the difference is the number of oxygen atoms.

Sorry I forgot to type at 4.0ppm

Thank you for leading me on the right way in identifying this therapeutic compound.  Unfortunately, being new to nmr, I am unfamiliar with the terms associated with it.  What does MF mean?

I'm not sure, to be honest.

Based on the IR data, I was thinking that there may be an amide functional group, but I'm not sure based on the NMR. How do I know that there is no amide functional group from the NMR data?

There is no nitrogen as the MS indicates.
As Orgopete said count the atoms.
The ¹HNMR provides the number of protons, the ¹³C the number of carbon atoms (provided there is no overlap). Work out the mass and subtract it from the mass given in the MS, this should indicate how many O atoms there are in the molecule.
Have a look here for chemical shifts of groups around 4ppm.

Therapeutic oils are rarely pure and often mixtures. Is yours?

MF is molecular formula

From 13C-NMR, C8.
From 1H-NMR, H8.
From MS, MW 152.
152-96-8=48
How many oxygens with 48 mass units? Three.
With C8H8O3, a benzene ring, and hydrogen ratios of 1:1:1:2:3, what are the possibilities, remember the benzene ring has four of the hydrogens?
Hint, what unit has three hydrogens?
