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

Multiple Choice

In a transition from one vibrational state to another, a molecule emits a photon of wavelength $5.56$ $\mu \mathrm { m }$ . 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) $13.6 \mathrm { eV }$
