Explain why a ketone carbonyl typically absorbs at a lower wavenumber than an aldehyde carbonyl (1715 vs. 1730 cm−1).
Calculate the wavenumber of the rotational transition from J=1 to J=2 of the HCl bond. The reduced mass of the molecule is 1.61x10-27 kg and its bond length is 1.275 Angstroms.
What types of bonds are responsible for the absorptions above 1500 cm−1 incompounds A and B ?
