A molecule of oxygen comes in contact with an IR photon with the frequency that matches the vibrational frequency of the stretching of the O=O bond. What change(s) occur in the molecule?Question 18AnswerThe molecule absorbs the photon and the frequency of the stretching of the O=O bond increases.The molecule absorbs the photon and the amplitude of the stretching of the O=O bond increases.The molecule absorbs the photon and the amplitude of the stretching of the O=O bond decreases.The molecule absorbs the photon and no change occurs.The molecule does not absorb the photon and no change occurs.The molecule absorbs the photon and the frequency of the stretching of the O=O bond increases.
