Vibrational autoionization in polyatomic molecules.

摘要: The vibrationally autoionizing Rydberg states of small polyatomic molecules provide a fascinating laboratory in which to study fundamental nonadiabatic processes. In this review, recent results on the vibrational mode dependence autoionization are discussed. general, rates depend strongly character normal driving process and electronic electron. Although quantitative calculations based multichannel quantum defect theory available for some molecules, including H 3 , only qualitative information exists most molecules. This review shows how information, such as Walsh diagrams along different coordinates molecule, can insight into rates.
