Document Summary
Here i"d like to give my method on solving nmr questions. I find it easier to go through all nmr questions in a similar approach. The degrees of freedom are very helpful in trying to piece together the structure of the compound. To calculate the degrees of freedom, use the following formula: For example, to find the degrees of freedom for the structure above, [(7 x 2) + 2 + 1 6 1]/2 = 5. Keep this in mind when you try to figure out the structure of the compound. Make sure the compound you draw matches the number of degrees of freedom: step 2: identify the functional groups that are present in the nmr: now look at the nmr and look at where the shifts are. Based on the location of the shifts, identify the functional groups that are present in the compound. A picture for dr. biewer"s notes regarding the shift location is shown below.
