A Certain Diatomic Molecule Emits a Photon of Energy 1

question 19

Multiple Choice

A certain diatomic molecule emits a photon of energy 1.20 eV when it makes a transition from the n = 1 vibrational state to the next lower vibrational state.If the molecule made a transition from the n = 2 state to the n = 1 state,what would be the energy of the photon it would emit? (h = 6.626 × 10^-34 J • s,h = 1.055 × 10^-34 J • s,1 eV = 1.60 × 10^-19 J)

• A) 3.60 eV
• B) 2.40 eV
• C) 1.20 eV
• D) 0.60 eV
• E) 0.30 eV
