Abstract
Our review of nonadiabatic bound states begins with a discussion of a quantum formalism first developed over 25 years ago. This formalism has recently been remarkably successful in providing a complete quantitative analysis of a molecular vibronic spectrum, as discussed below. However, the intractability of the quantum approach for treating larger systems remains an outstanding problem. Experimental manifestations of bound state nonadiabaticity are reviewed next, with an emphasis on isolated molecules. Two exceptionally promising developments are highlighted, both relating to Rydberg states. Finally, several semiclassical theories of nonadiabatic processes are briefly reviewed, and vibronic dynamics in the vicinity of a conical intersection are explored within the framework of the classical electron model.
