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 4 eV. When the molecule undergoes a vibrational transition from one energy state tc the next lower energy state, it gives up 0.2540 eV. Find the force constant of this molecule.
