When a hypothetical diatomic molecule having atoms 0.8890 nm apart undergoes a
rotational transition from the l= 2 state to the next lower state, it gives up a photon having
energy 8.850 * 10-* eV. When the molecule undergoes a vibrational transition from one
energy state to the next lower energy state, it gives up 0.2540 eV.
Find the force constant of this molecule.

The force constant for the internuclear force in a hydrogen molecule (H2) is k′ = 576 N /m. A hydrogen atom has mass 1.67 * 10-27 kg. Calculate the zero-point vibrational energy for H2 (that is, the vibrational energy the molecule has in the n = 0 ground vibrational level). How does this energy compare in magnitude with the H2 bond energy of -4.48 eV ?
