1H NMR

Yesterday was a continuation of NMR, except we looked at the NMR of hydrogen rather than carbon. The concepts are the same, with an exception or two.....the main difference that we saw was that there is a quantitative aspect to 1H NMR that is not present in 13C NMR. It is possible to do an integration of the peaks, which will give us a relative ratio of the number of hydrogens responsible for each signal. Yesterday, all of the peaks were single peaks, on Friday we will look at how peaks can have different multiplicities -- there was some foreshadowing when I mentioned the N+1 Rule at the end of class.

Many changes have been made to the left: The Need to Knows for Chapters 13, 14 and 15 have been posted, as have the charts for 13C and 1H NMR. (Remember, you'll be given the 13C chart but must learn the 1H chart.) Modeling exercise #10 has also been posted; I'll talk more about it tomorrow.

New changes! A key for the exam and an NMR problem set have been posted. The problem set key will be posted once I get it cleaned up a bit and I'll have a group NMR activity for you tomorrow.
