In a Transition from One Vibrational State to Another, a Molecule

question 165

Multiple Choice

What is the energy difference between these two states? $\left( c = 3.00 \times 10 ^ { 8 } \mathrm {~m} / \mathrm { s } , h = 6.626 \times 10 ^ { - 34 } \mathrm {~J} \right.$ $\cdot \mathrm { s } , 1 \mathrm { eV } = 1.60 \times 10 ^ { - 19 } \mathrm {~J}$ )

• A) \(2.23 \mathrm { MeV }\)
• B) \(0.223 \mathrm { eV }\)
• C) \(0.223 \mathrm { MeV }\)
• D) \(13.6 \mathrm { MeV }\)
• E) \(13.6 \mathrm { eV }\)
