摘要
芳香化学在近几十年内得到了很好的发展。随着HMO法在有机化学中的应用，先后出现了(4m+2)规则、二倍规则和REPE指标等三种判断环状化合物的芳香性的推理方法。但是，对于某一化合物是否具有芳香性这一问题，至今尚缺乏简单明确和直观性的实验判据。
A series of Physical Properties of aromatic heterocyclic compounds such as Pyrazolones and aromatic hydrocarbons in solid state has been investigated by qualitative experiments. These aromatic compounnds are found to possess four effects: electrostatic effect, thermal sensitive effect, fluorescent effect and crystal cleavability.The observed four physical effects may be interpreted in terms of an aromatic ring structure belonging to such or all type of aromatic compounds.Based on observations described above,we have suggested that the four Physical effects can be used as some new criteria on judging aromaticity.
