Suppose we measure the wavelengths of the absorption lines of a vibrating diatomic molecule involving atoms whose masses we know. From this data, we can deduce the effective spring constant $k_{s}$ of the bond holding these atoms together.

Question

Quizplus · Accepted Answer

The effective spring constant $k_{s}$ of the bond in a diatomic molecule can be deduced from the wavelengths of the absorption lines, as these wavelengths are related to the vibrational frequencies of the molecule, which in turn depend on the masses of the atoms and the spring constant according to the quantum mechanical model of a diatomic molecule.
