A transition of particular importance in 02 gives rise to the 'Schumann-Rung c band' in the ultraviolet region. The wave numbers (in cm-1) of transitions from the ground state to the vibrational levels of the first excited state (3Σ-) are 50 062.6, 50 725.4, 51369.0, 51988.6, 52579.0, 53143.4, 53679.6, 54177.0, 54641.8, 55078.2, 55460.0,55 803.1, 56107.3, 56 360.3, 56 570.6. What is the dissociation energy of the upper electronic state? (Use a Birge-5poner plot.) The same excited state is known to dissociate into one ground-state °atom and one excited-state atom with an energy 190 k} mol-3 above the ground state. (This excited atom is responsible for a great deal of photochemical mischief in the atmosphere.) Ground-state 02 dissociates into two ground-state atoms. Use this information to calculate the dissociation energy of ground-state 02 from the 5chumann-Runge data.
