Homework Help: Quantum oscillator

  1. Aug 14, 2008 #1
    if the quantum oscillator was used to describe a diatomic molecule, then at T=0, the molecule shouldnt be vibrating at all. but using the quantum oscillator model, the molecule still has a minimum energy at its ground state related to its zero point energy. does this mean a molecule at T=0 DOES vibrate still?

    In my opinion:
    This implies that molecules are not completely at rest, even at 0K. Zero point energy = minimal energy of oscillation. On the other hand 0K means no kinetic energy, so we cannot achieve 0K.
