The vibrational wave number of the oxygen molecule in its electronic ground state is 1580 cm3, whereas that in the first excited state (B 3L), to which there is an allowed electronic transition, is 700 cm3, Given that the separation in energy between the minima in their respective potential energy curves of these two electronic states is 6.175 eV, what is the wave number of the lowest energy transition in the band of transitions originating from the v = 0 vibrational state of the electronic ground state to this excited state? Ignore any rotational structure or anharmonicity.
