Question

2. Consider a 1D harmonic oscillator where x is the displacement of the bond length r from its equilibrium value (x= r-r.) As the vitrational quantum number n increases, the most probable value of x (a) Is constant (b) Moves to more negative x values (c) Moves to more positive x values (d) B and C (e) None of the above 3. The vibrational motion of a diatomic molecule is most accurately modeled by a 1D harmonic oscillator when (a) The molecule is in its vibrational ground state (b) The bond distance is near the equilibrium value (c) The vibrational energy level is near the dissociation limit (d) A andbB (e) B and C (1) None of the above

Explanation / Answer

2) the most probable value of x is constant.

3)diatomic molecule is most accurately modelled by a 1D harmonic oscillator when the molecule is in its vibrational ground state.
