论文摘要
芳族碳氢化合物pyrene（c $ _ {16} $ h $ _ {10} $）和冠状（C $ _ {24} $ H $ _ {12} $）的低能共振（c $ _ {16} $ _ {10} $）和冠状（C $ _ {24} $ _ {12} $）的方法是根据一种基于$ hubbard $ y的模型的方法来研究的。使用独立子系统近似，其中使用周长和内部碳原子为独立实体。由于在只有外围碳原子的芳族碳氢化合物中未发现低能共振，因此我们将pyrene和concoronene的低能共振归因于内部碳原子。但是，具有五个内部碳原子的corannulene（c $ _ {20} $ h $ _ {10} $）在实验数据中不会表现出低能共振。我们将这种共振的缺乏归因于内部碳原子的奇数。
The low energy resonance in the double photoionization of the aromatic hydrocarbons pyrene (C$_{16}$H$_{10}$) and coronene (C$_{24}$H$_{12}$) is investigated theoretically using an approach based on the one-dimension Hubbard model for $π$-conjugated systems with nearest-neighbor interactions. The Independent Subsystem Approximation, where the perimeter and interior carbon atoms are treated as independent entities, is employed. Since no low energy resonances have been found in aromatic hydrocarbons where there are only perimeter carbon atoms, we attribute the low energy resonances in pyrene and coronene to the interior carbon atoms. However, corannulene (C$_{20}$H$_{10}$) having five interior carbon atoms does not exhibit a low-energy resonance in the experimental data. We attribute the absence of this resonance to the odd number of interior carbon atoms.
