UNKNOWN ORGANIC COMPOUND?? PLEASE!

Hi,
So, I was given an organic compound by my professor and we were supposed to figure out what it is by chemical tests and spectroscopy. I figured out that its an ester and now I have the IR spectrm

Here is the NMR, but its kind of crappy:

The boiling point was a little bit finicky, so I ended up with something between 86-99. In that range, I have 10 compounds:
- isopropyl acetate
- methyl isobutyrate
- 2-propenyl acetate
- tert butyl acetate
- ethyl propionate
- methyl methacrylate
- methyl pivalate
- ethyl acrylate
- propyl acetate
- methyl butyrate
I didn't do a test for unsaturation, but I dont think it is a double bond based on the really crappy CNMR spectrum I was given
So far, I have just been googling IR/NMR spectrums and it kind of seems like it could be t-butyl acetate or propyl acetate, but i dont know im kind of lost. Please help its due tonight.

If you have a
13
C NMR, post it. The
1
H NMR you have is useless, it looks like something went wrong and it should be re-run. It doesn't match any of your 10 options.
