摘　　要：本文中提出分子聚合物中间态耦合振动预离解理论。其中明确提出了分子中间态在诱导分子聚合物振动预离解过程中的重要作用,并由此建立了统计动力学模型以定性和半定量地描述和解释各种分子聚合物的实验峰宽效应。文中还讨论了各种耦合机制对分子聚合物能级结构和态弛豫过程的影响。In this paper, a theoretical model for vibrational predissociation (VP) of molecular clusters via intermediate states is proposed. It is shown that molecular intermediate states play an important role in inducing VP processes of molecular clusters. Based on this theory, a statistical dynamics model is established to describe and interpret qualitatively and semiquantatively the experimental line-broadening effects in various molecular clusters. Finally, we discuss the effects of a variety of coupling mechanisms on the energetic structures and the state relaxation processes in molecular clusters.
