Notice the indices at the bottom and top. The top graph is your C13 NMR and the bottom is your proton NMR. You need a few more pieces than what's given here to interpret the structure. The first thing you need to know is the chemical formula. That will give you insight on where to start. The area under each individual set of peaks tells you how many hydrogens there are relative to the whole molecule giving that specific signal. So if i have CH3-CH=CH-CH3, you would expect to see 6 times the area under the peaks for the CH3 rather than the CH. The splitting pattern tells you how many hydrogens you have connected to whatever the hydrogen that gave that signal is connected to. So for my example, the H on the CH would be split into 5 peaks. The number of peaks minus one tells you how many hydrogens are attached. I can be more help if you have the chemical formula!
