波包动力学伴随着激发到一个衰减的电子状态和随后的衰减到最终的电子状态进行了讨论。激发和产生末态的截面与相应的波包有关。与时间有关的配方增加了洞察的过程，并服从半经典近似和解释。它也可以用来计算通过光谱矩展开的观测光谱的总特征。一个说明性的应用程序演示了扩展的有用性。
The wave packet dynamics accompanying the excitation to a decaying electronic state and the subsequent decay to final electronic states are discussed. The cross sections for the excitation and for the production of final states are related to the corresponding wave packets. The time-dependent formulation adds insight into the process and is amenable to semiclassical approximations and interpretations. It can also be used to compute the gross features of the observed spectra via a spectral moment expansion. An illustrative application demonstrates the usefulness of the expansion.
