Question

A diatomic molecule is modeled as a Morse oscillator, and one finds that its energy level
differences decrease from E2 - E₁ = 1374.2 cm-¹ to E7 - E6 = 1139.6 cm ¹.
(a) Use this information and the quantum energy levels for the Morse oscillator to find the
harmonic angular frequency, w, in cm-¹.
(b) What is the dissociation energy, D (in kJ/mole) for this Morse oscillator?
(Note that the energy units, 11.9627 J/mole = 1 cm-¹.)
