question 27

Multiple Choice

A diatomic molecule is vibrating in its first excited quantum state above the ground state. In that excited state, its frequency is 2.0 × 10¹³ Hz. What is the energy of the molecule in this state? (h = 6.626 × 10^-34 J ∙ s, = 1.055 × 10^-34 J ∙ s, 1 eV = 1.60 × 10^-19 J

• A) 0.041 eV
• B) 0.083 eV
• C) 0.12 eV
• D) 0.15 eV
• E) 0.17 eV
