It is important to realize that not all molecular vibrations lead to oscillating dipoles.

The radiation involved is normally of frequency much greater than that of any molecular vibration.

But there are some molecular vibrations which cannot interact with this radiation.

In nonradiative or dark decay, energy is given off via molecular vibrations (heat).

In molecules with three or more atoms, the number of degrees of freedom for molecular vibrations is at least 3.

IR in particular is used to see atomic and molecular vibrations.

The thing about molecular vibrations is that they have specific frequencies, called modes.

Absorption of radiation is followed by molecular vibration to the S state.

The absorption of infrared light by organic molecules causes molecular vibrations.

It is also possible to observe molecular vibrations by an inelastic scattering process.
