E. Mayer et al., STATE-TO-STATE DYNAMICS IN THE HIGH RYDBERG STATES OF POLYATOMIC-MOLECULES, Philosophical transactions-Royal Society of London. Physical sciences and engineering, 355(1729), 1997, pp. 1569-1582
Rydberg states in polyatomic molecules exhibit dynamics that bear on i
ssues of longstanding importance for theory. Coupling is made complica
ted, however, by the presence of many rovibrational degrees of freedom
and the existence of multiple pathways for intramolecular relaxation.
In work on vibrationally autoionizing states of HCO and NO2, we have
applied multiple resonance excitation strategies to isolate single rov
ibrational Rydberg-Rydberg transition, the positions, lineshapes and i
ntensities of which reflect coupling strengths for state-detailed rela
xation processes.
