Consider a N₂ molecule in its first excited electronic state, that is, when an electron in the highest occupied molecular orbital (HOMO) is promoted to the lowest unoccupied molecular orbital (LUMO). Identify the molecular orbital involved and sketch a diagram to show the transition. Compare the bond order and bond length of N₂* with N₂, where the asterisk denotes the excited molecule. Is N₂* diamagnetic or paramagnetic?

q3

Consider a N2 molecule in its first excited electronic state, that is, when an electron in the highest occupied molecular orbital (HOMO) is promoted to the lowest unoccupied molecular orbital (LUMO). Identify the molecular orbital involved and sketch a diagram to show the transition. Compare the bond order and bond length of N₂* with N2, where the asterisk denotes the excited molecule. Is N₂* diamagnetic or paramagnetic? When N₂* loses its excess energy and converts to the ground state N2, it emits a photo of wavelength 470 nm, which makes up part of the aurora lights. Calculate the energy difference between these level.
