The vibration of a diatomic molecule such as HI may be represented by the harmonic

oscillation of a single mass, $\backslash$mu $,$ known as the effective mass. Apply the simple harmonic oscillator model and so make an estimate of the force constant of the H$$I bond, given that the wave$-$number for the transition from v $=1$ to v $=0$ is $2310$ cm$1.$ Express the frequency of the transition in Hz$.$
