The spectral behavior of molecular aggregates has been successfully understood in terms of Kasha’s model. In this issue of Chem, Chuang et al. describe a generalization to explain the spectral behavior of two-dimensional molecular aggregates. They provide a spectral handle to determine the slip between molecules in the two-dimensional packing.

解开二维激子系统中的分子堆积

分子聚集体的光谱行为已经成功地按照Kasha模型进行了理解。在本期《化学》杂志上，Chuang等人。描述一个概括来解释二维分子聚集体的光谱行为。它们提供了光谱处理，可确定二维堆积中分子之间的滑动。
