WebMar 16, 2024 · It might be worth noting that a molecule such as hydrogen chloride (HCl) does absorb infrared light. In order for a vibration to absorb infrared radiation and become excited, the molecule must change its dipole moment during the vibration. Homonuclear diatomic molecules such as N 2 and O 2 do not have dipole moments.
