“…If a n electron is excited from one antibonding v* MO of (1) to the other, higher energy MO configurations such as (3) are obtained, from which the Lewis Formula (I) may be generated. This excited configuration has been estimated to lie 1.3 electron volts above the ground state configuration [9]. …”

AbstractsThe molecular orbital configuration for the ground-state of 0, generates the valence formula -0 -0 -. "Increased-valence" formulae for triatomic and polyatomic molecules have been developed recently. In them, more electrons participate in bonding than is possible for the familiar valence-bond formulae. Using oxyhaemoglobin as an example of an oxygen carrier, various increased-valence formulae are generated for the FeO, groups. In the low-energy formulae, the iron is bonded to the above valence formula for 0,. Therefore, in contrast.to the bonding schemes of Pauling and Coryell, Griffith and Weiss, little reorganization of 0, need occur on formation of HbO, . This conclusion is independent of the mode of co-ordination of iron to the 0, .
