Answer:
The frequencies and intensities of the fundamental and overtone bands of the carbonyl group vibration in a large number of compounds have been measured. The results suggest that data on the band intensities can help to resolve ambiguities in structural determinations where groups of different character have the same vibration frequency. The variations in both frequency and intensity have been considered in relation to the inductive and resonance properties of the attached groups. The results suggest that inductive effects largely control the variation of vibration frequency in different compounds, but the intensity is more dependent upon mesomeric effects.
