Theoretical and Experimental (Electron Impact) Studies of Low-Lying Rydberg States in O2.
Abstract
Theoretical studies of the n = 3, 4, and 5 Rydberg series in O2, converging to O2(+)(X doublet Pi(g)), are presented and correlated with electron energy-loss spectra of molecular oxygen, in the region from 7.0 to 10.5 eV. The angular dependence determined for various features in the energy-loss spectra have been correlated with the known behavior for transitions between electronic states of certain symmetry, and with the theoretical results, to identify the low-lying Rydberg states. Four vibrational levels of the (3 s sigma(g)) triplet Pi(g) Rydberg state have been observed superposed on top of the maximum intensity portion of the Schumann-Runge continuum. The theoretical results, combined with the energy-loss measurements and the high resolution photon absorption work, lead to the assignment of the lowest dipole-allowed Rydberg states.
