通过从线性多烯链到具有蜂窝结构的平面分子等几个例子，说明了π电子在一维和二维区域受限的效应。对分子材料的理论计算和特定的拉曼实验表明，分子方法为解释线性多共轭聚合物（聚乙炔）和纳米结构石墨材料的拉曼响应提供了一个统一的关键。
The effect of the confinement of pi electrons in one- and two-dimensional domains is illustrated with several examples ranging from linear polyene chains to planar molecules with honeycomb structure. Theoretical computations and specific Raman experiments on molecular materials demonstrate that a molecular approach provides a unified key to the interpretation of the Raman response both of linear polyconjugated polymers (polyacetylene) and of nanostructured graphitic materials.
