1.  The peak in the IR labelled 1687 will tell you the nature of the oxygen.

2.  Use the DEPT-135 and DEPT-90 experiments to sort out the number of H on each carbon - it's easier to use than the integration on the ¹H spectrum

3.  Remember what the peaks at 7-8 ppm in the ¹H spectrum mean.

4.  Related to #3 - the ¹³C peaks from 128-137 ppm (including the DEPT experiments) will tell you the substitution pattern
