The ultraviolet photoelectron spectrum of F2O was recorded with a higher resolution than previously published. New vibrational structure was observed in the second and third bands. Near state-of-the-art molecular orbital calculations were performed on the X̃ A1 state of F2O and the X̃ B1 , B2 , A1 , and A2 state of F2O , and their potential energy functions were computed. Spectral simulations bas...
