When absorbing energy the molecule can behave in different ways:

  • translation - whole molecule moving
  • rotation - of the whole molecule
  • vibration - of the bonds
  • electron energy

Increasing energy needed:

Translatinonal > Rotational > Vibrational > Electronic

  • Electronic energy changes as electrons move energy levels - elecrtonic energy is quantised with fixed levels
  • ALL
