摘要：
Vibronic coupling of SIGMA and PI-Rydberg series in linear polyatomic molecules is analyzed within a simple multi-channel quantum-defect-type model. The static (potential-energy surfaces of Rydberg states) and dynamic (absorption and photoionization cross sections) aspects of the model are analyzed. The model describes non-Born-Oppenheimer vibronic effects in low Rydberg members, resonant inter-Rydberg perturbations in the range of intermediate principal quantum numbers, as well as vibronically induced autoionization of high Rydberg levels in a coherent manner.
