Three of the bands have vibrational fine structure. The fourth band, which is from the least energetic ionization, shows no such fine structure. Explain these results in terms of your MO scheme. 2) If we added two more electron pairs to the MO scheme for BeH2, this would describe the bonding in water if water were a linear molecule. Compare your MO scheme for bent water with this hypothetical scheme for linear water, and comment on why water is bent instead of linear.arrow_forwardDescribe the bonding (including sigma and pi bonds) on an N atom in dinitrogen difluoride,N2F2 using valence bond theory.arrow_forward
