Answer:
True
Explanation:
Infrared spectroscopy is concerned with transitions between vibrational energy levels in molecules.
The vibrations that are found to be infrared active in molecules are those vibrations that result in a change of dipole moment in the molecule.
In the treatment of infrared spectroscopy, the covalent bond is treated as an elastic spring which can be stretched. The approach of the simple harmonic oscillator can be applied to the problem.
