Molecular orbitals and electronic populations (Fukui indices). H means HOMO (the highest occupied MO), the next upper occupied MO, the second next upper occupied MO, L the LUMO (the lowest unoccupied MO), the second lowest unoccupied MO, and the third lowest unoccupied MO. The circles depict those MOs in which an atom has a nonzero electron population.
