Diatomic molecules such as H2 and O2 undergo simple harmonic motion with frequencies that obey Hooke's Law, with an effective mass equal to half the atomic mass. If the mass of an oxygen atom is 2.66 × 10−26 kg and the observed frequency of oscillation is 4.66 × 1013 Hz, what is the effective spring constant associated with the bond between the atoms in an oxygen molecule (O2) ?
