The most common applications of symmetry to spectroscopy involve vibrational and electronic spectra.

The vibrational spectra of many oxohalides have been assigned in detail.

It is also possible to record vibrational spectra of solid samples under high and varying pressure.

Now we must consider in more detail some of the ways we may use vibrational spectra to give structural information about inorganic substances.

This is a traditional approach, and probably accounts for most vibrational spectra actually recorded.

Such structural changes are of course accompanied by changes in vibrational spectra.

Among these are the alkali halides, for many of which he obtained the first vibrational spectra.

For accurate reproduction of vibrational spectra, the Morse potential can be used instead, at computational cost.

Changes in rotational state give fine structure to the vibrational spectrum.

In 1929 he proposed the Morse potential function for diatomic molecules which is used to interpret vibrational spectra.
