Puckering Energetics and Optical Activities of [7]Circulene Conformers

Masashi Hatanaka2016-02-01The Journal of Physical Chemistry A

The structural preference of [7]circulene is analyzed by taking into account vibronic interactions. DFT calculations reveal that pseudo-Jahn-Teller effects cause the D7h-symmetry structure to relax to C2- and Cs-symmetry structures, which are both ca. 9 kcal/mol lower in energy than the D7h structure. In energy terms,…
