“…These characteristics have permitted the use of REMPI for sensitive detection of radicals, which are important in areas such as atmospheric chemistry and combustion processes, using tunable laser radiation in the visible or ultraviolet region [1][2][3]. In the present work, REMPI spectroscopy has been used to investigate low-lying Rydberg states of SO(X32 ), a molecule which is important in atmospheric chemistry [4,5] and in the combustion chemistry of sulfur compounds [6,7].…”

Rydberg states of the SO molecule, in the region 62 500-67 500cm -1 above the neutral ground state, have been studied using both (3 + 1) and (2 + 1) resonance enhanced multiphoton ionization (MPI) spectroscopy. Band assignment has been assisted by recording spectra with both linearly and circularly polarized radiation, by simulation of rotational band contours and by calculating quantum defects for the observed Rydberg states.Transitions to four Rydberg states (the 3A(4pn), 3I'I(3dc5), 3I-I(3do') and 3q~(3d6) states) have been observed corresponding to promotion of an electron from the outermost occupied n molecular orbital in SO(X3E -) to the 4pn, 3d6 and 3da Rydberg orbitals. For each state, spectroscopic constants have been derived from the experimental spectra. A (2 + 2) MPI spectrum of a known valence state, the B3y~ -, v' = 8 state, has also been obtained.

“…Since the initial report of a new oxide of sulfur by Schenk in 1933, 29 the highly reactive S 2 O system has suffered a long history of mistaken identity and muddled spectral interpretation. Erroneous determinations of chemical stoichiometry 30,31 led to several proposed geometries based on a sulfur-to-oxygen ratio of unity.…”

Emission spectra obtained from jet-cooled disulfur monoxide (S 2 O) molecules have been interpreted by means of a novel Lie algebraic formalism that makes possible the facile evaluation of multidimensional Franck-Condon factors. Fluorescence accompanying selective excitation of isolated vibronic bands in the S 2 O C 1 AЈ-X 1 AЈ(*-) absorption system has been dispersed under moderate spectral resolution, allowing assignment of ground state levels possessing up to 20 quanta of vibration in the 2 S-S stretching mode ͓E vib (X )р13 900 cm Ϫ1 ͔. Aside from providing a rigorous and economical description for the inherently anharmonic nature of highly-excited polyatomic species, our algebraic approach enables quantitative information on molecular wavefunctions to be extracted directly from spectroscopic data. The emerging picture of S 2 O vibrational dynamics suggests that the X 1 AЈ potential surface is substantially more ''local'' in character than the C 1 AЈ manifold. While the observed pattern of X 1 AЈ vibrational energies could be reproduced well through use of model Hamiltonians that include only diagonal anharmonicities in the local algebraic basis, successful treatment of the C 1 AЈ state necessitated explicit incorporation of off-diagonal anharmonicities that lead to pervasive mixing of local vibrational character. This disparate behavior is manifest strongly in measured C -X transition strengths, thereby allowing detailed investigations of Franck-Condon intensities to discern the underlying dynamics. Structural parameters deduced from algebraic analyses are in good accord with previous predictions of the change in S 2 O geometry accompanying *-excitation.

“…[3] Early reports describe the trapping and characterization of SO in an argon matrix [4] but it was only first observed only in the early 1930s. [5] Since then, chemists have exploited transition metal complexes to stabilize this reactive diatomic molecule, although few examples are known.…”
