Hydrogen abstraction natural orbital correlation diagram

Figure 4.17. a) Natural orbital correlation diagram for hydrogen atom abstraction by a carbonyl compound and b) orbital correlations after introducing interactions between orbitals of equal symmetry. 

Figure 7.Z3. Perpendicular hydrogen abstraction reactions a) the natural orbital correlation diagram and b) the resulting state correlation diagram (adapted from Bigot, 1980).

Figure 4.18. State correlation diagram for hydrogen atom abstraction by a cai nyl compound derived from the natural orbital correlations. The configuration correlations are shown by dotted lines, taking into account the interaction yields the correlations shown by solid and broken lines for singlet and triplet states, respectively.
