State correlation diagrams Dauben-Salem-Turro

The mechanism of photoenolization in 1-methylanthraquinone has been studied in detail (Gritsan, N. P. Khmelinski, I. V. Usov, . M., J. Am. Chem. Soc., 1991, 113, 9615). The reaction was found to occur in both the singlet and triplet (nn ) states. Develop a Dauben-Salem-Turro state correlation diagram for the photochemical step and, on the basis of your diagram, discuss the efficiency of the reaction... 

This question involves the analysis of carbonyl photochemistry using Dauben-Salem-Turro state correlation diagrams. 

The photochemistry of l,5-hexadien-3-ones has been examined by Dauben and coworkers. A relatively rare dependence of the intramolecular enone-olefin photoaddition of several derivatives has been observed. Discuss the mechanistic possibilities in terms of Dauben-Salem-Turro state correlation diagrams. (See Dauben, W. G. Cogen, J. M. Ganzer, G. A. Behar, V., J. Am. Chem. Soc., 1991, 113, 5817.)... 

In Chapter 15, the state correlation diagram approach of the previous chapter is applied to a brief discussion of photochemistry in the manner of Dauben, Salem, and Turro [13]. A more comprehensive approach to this subject may be found in the text by Michl and Bonacic-Koutecky [14], Turro [15], or Gilbert and Baggott [16].
