7.5 Exercise 1

The vibrational frequency of the hydrogen iodide HI diatomic molecule is $6.69 \times 10^{\textrm{ } 13} \text{Hz}$. (a) What is the force constant of the molecular bond between the hydrogen and the iodine atoms? (b) What is the energy of the emitted photon when this molecule makes a transition between adjacent vibrational energy levels?
