A transition of particular importance in O2 gives rise to the Schumann-Runge ban

Question

A transition of particular importance in O2 gives rise to the Schumann-Runge band' in the ultraviolet region. The wavenumbers (in cm -1) of transitions from the ground state to the vibrational level of the first excited state are 50062.6, 50 725.4, 51 369.0, 51 988.6 52 579.0,, 53 143.4, 53 679.6, 54 177.0, 54 641.8.55 078.2, 55 460.0. 55 460.0 55 803.1, 56 107.3., 56 360.3,56 570.6. What it the dissociation energy of the upper electronic state? (Use a Birge-Sponer plot.) the same excited state is known to dissociate into one ground-state O atom and one excited-state atom with an energy 190 kJ mol-1 above the ground state. (This excited atom is responsible for a great deal of photochemical mischief in the atmosphere.) Ground-state O2 dissociates into two ground-state atoms. Use this information to calculate the dissociation energy of ground-state O2 from the Schumann-Runge data.
