ABSTRACT
Acenaphthylene (ACN), which forms bright yellowish plates with a melting point of 93-94˚C, is one of the simplest nonalternant aromatic hydrocarbons.
Since its discovery by Dziewonski and Rapalski in 1912, the photochemical conversion of ACN into two isomeric dimers (
cisoid
-
and
transoid
-
) has been studied because of its unique photophysical properties and mechanistic interest.
