Answer:

The physical meaning of the vibrational selection rule is this: The vibration must change the molecular dipole moment to have a non-zero (electric) transition dipole moment. ... As the molecule stretches and compresses itself in its one vibrational mode, the symmetry is unchanged, and at no time does a dipole moment exist.
