Fluorine emission spectrum
WebThe idealized PES spectrum of an unknown element. The spectrum shows five peaks, one with a binding energy near 100 MJ/mol, two with binding energies near 10 MJ/mol, two with binding energies near 1 MJ/mol. From left to right, the relative intensities of the peaks are 2x, 2x, 6x, 2x, and 1x.
