✦ Synopsis
The concIusions of the preceding paper concerning the mechanism of interna dimerization of linked anthracenes are reviewed. The new data are found consistent with a previously proposed biradical mechanism.

Fluorescence and photocyclomerization quantum-yield measurements and a transient kinetic analysis were performed for a series of u,w-fbis-9-anthryl)-fi-~anes (4Ca-X to ACro-A and A-tiy-A) in methylcyclohesane and ethanol. Of note is an irregular periodicity of intramolecular escimer fluorescence yie
