¹H NMR Chemical Shift: H-C(sp³)-R R = H, C(sp³) R = C(sp²) R = O, N, X Y = C (regular alkene) Y = C (benzene ring) Y = O (aldehyde) 0-2 ppm -2 ppm -4 ppm 4-6 ppm 6-8 ppm 10 ppm H-C(sp²)-R Hydrogens bonded to O, N, or S can show up anywhere on an NMR spectrum. They are usually broad singlets. Multiple electron-withdrawing groups lead to somewhat higher chem. shifts, e.g. a hydrogen bonded to an sp³-hybridized carbon that is also bonded to an oxygen and an sp²-hybridized carbon might show up around 5 ppm rather than ~2 ppm or ~4 ppm. Multiplicity: A signal is split into a new shape based on the number and types of neighbors, following the n+1 rule. (1 neighbor = 2 lines = doublet) The space between these lines is known as the coupling constant. For every different type of neighbor, you get another splitting following the n+1 rule (1 neighbor A and 2 neighbors B gives a doublet of triplets or a triplet of doublets, they are the same). 13C NMR Chemical Shift: C(sp³) attached to other…
