Molecules' bonds vibrate at all temperatures, which manifests e.g., by change of bond lengths, or (intermolecular) bond angles. At $T = \pu{0 K}$, molecules still vibrate, too. The energy in electromagnetic radiation is discontinous, discrete (you recall $\hbar$). For some energies in electromagnetic radiation, the electric field vector brings to the ...
