Two atoms in a diatomic molecule (masses m1 and m2) interact through a potential energy function of the form u(r) = a 4r 4 − b 3r 3 , where a and b are constants and r is the separation of the atoms. a) find the equilibrium separation of the atoms and the frequency of small oscillations about equilibrium, assuming the molecule does not rotate. how much energy must be supplied to the molecule in equilibrium in order to break it up (that is, so that r → [infinity])?
