## Abstract The ^17^O and ^13^C chemical shifts (δ) of 14 α,β‐unsaturated aldehydes and ketones and 33 acyl derivatives RXC = O (X = Cl, OH, OMe, OEt, NH~2~ and R = H or alkyl) have been measured. In the unsaturated carbonyl series, a correlation exists between δ ^17^O and the π electron density at
