It requires calculating the momentum of a photon needed to transition a molecule from its ground state to the next lowest energy state. The solution involves understanding the mass of the atoms, the bond length, and the angular frequency of vibration, ultimately leading to the determination of the photon's momentum necessary for the transition."}
