โœฆ Synopsis

This article is a brief survey on studies found in the literature on the development of photoreactive and thermal processes of halogenocyclohexadienones in organized media. Cyclohexadienones belong to the elaas of compounds known as "blocked aromatic molecules"1"2, that is, compounds in which the presence of a single tetrahedral atom prevents the molecules from conversion to aromatic molecules. They are of two types : ortho-dienones of type A or cyclohexa-2,4-dien-l-ones, and para-dlenones of type B or cyclohexa-2,5-dien-l-ones. The numbering of the atoms in these molecules is as follows:

Theoretical arguments are presented indicating that the mtermolecular translational frequency in solid-state chargetransfer compIexes and dimers decreases upon electronic excitation\_ These arguments are used to explain some features of the spectrum of solid authracene-PMDA. \* Issued as NRCC No. 19
