Autoionization states of SO2

摘要

We report the assignments of five autoionizing states of SO2in the 960ndash;810 Aring; region. The experimental data used in the present analysis have been previously obtained by a molecular beam photoionization mass spectrometry. The observed vibrational progressions are tentatively assigned to the following Rydberg transitions: 4b2rarr;3s, 4b2rarr;3d, 7a1rarr;3p, 7a1rarr;3d, and 2b1rarr;3p. The window resonance series previously reported lsqb;C.Y.R. Wu and D. L. Judge, J. Chem. Phys. 74, 3804 (1981)rsqb; in a photoabsorption measurement is confirmed in the photoionization efficiency curves of SO+2and SO+.
