Abstract
1J(13CH) and 2J(13CH) involving the aldehydic proton in ortho‐alkylbenzaldehydes have been examined for evidence of a hyperconjugative contribution from the aromatic π‐electrons. The expected hyperconjugative effect is obscured by changes in the coupling constants resulting from steric inhibition of resonance.Keywords
