This is a standard reference point with the signal set exactly at 0 ppm and y ou can ignore it when analyzing an NMR spectrum. The b -carbon of the double bond is shifted to lower field by 20 to 30 ppm, and the carbonyl carbon is shifted to higher field by 5 to 15 ppm. There are a lot of compounds especially organometallics that give signal at negative ppm, but you will probably not need those in undergraduate courses. The O-H and N-H protons are exchangeable, and this is handy feature because when in doubt, you can add a drop of deuterated water D 2 O and make the signal disappear since deuterium does not resonate in the region where protons do:. Organic Chemistry Michigan State University. There are two reasons for this. Inductive deshielding effects of electronegative substituents are roughly additive, as the following data suggests. These signals are concentration and temperature dependent.
