How to deduce a structure from IR, NMR and MS spectra, Example 1

This is an example of how I deduce a structure from spectra. While I have read instructions or guide on how to do this in books, I realized that was not how I did them. In class, I simply illustrated how I did them. I have had it on my objectives to write out several examples of how to do this for some time, this is one of the first examples. Interestingly, this problem is probably more difficult compared to the kinds of problems I see in textbooks or posted by students.

Open the following pdf file:
Example problem

IR
NMR, NMR inset
MS

The IUPAC name for the structure is (E)-3-(4-methoxyphenyl)-1-phenylprop-2-en-1-one (a chalcone derivative).
