We did a NMR analysis on acetylacetone (2,4 pentadiene) and I'm suppose to just use the spectrum and determine the equilibrium constant. I have no clue on how to start it and its no use on asking the professor because he's also NMR illiterate. Can someone try and explain to me how to calulate this. I uploaded the picture of the NMR spectrum to a website because the file is too big to attach so you can just save it view it clearly. http://i66.photobucket.com/albums/h256/hello0s/acetylacetoneNMRSpectrum.jpg Thanks in advance.
