If the ring is inverted, the ester is moved into axial positions, leaving the carbonyl carbon sterically exposed on one side and sterically shielded by the ring on the other.
IR spectrophotometry (Bruker IFS 28) was used in transmittance mode to determine the absorbance of the carbonyl peak at ~1720 [cm.
Here the H-bonded site is preferred because the carbonyl carbon has increased positive character due to electrons being withdrawn by the H-bond (Fig.
