    摘要:
    Mercury-xenon arc lamp photolysis of argon matrix samples at 12 K containing hydrogen sulfide and sulfur dioxide produced eight new infrared absorptions at 2591, 1209, 1093, 762, 476, 450, 340, and 270 cm-1. Extensive deuterium and oxygen-18 isotopic substitution studies, and normal-coordinate calculations on all isotopomers, allow the assignment of these absorptions to eight vibrational modes of sulfinic acid. The HSO2H molecule is formed by in situ hydrogen atom addition to matrix-isolated sulfur dioxide molecules. This is the first infrared spectroscopic observation of this reactive molecule.

    Matrix Isolation of Diphenylsulfene and Diphenyl-α-sultine
    摘要:
    Diphenylsulfene (5) and diphenyl-alpha-sultine 6 were generated in cryogenic matrices by three independent routes: (i) the thermal reaction of diphenylcarbene (8) and SO2, (ii) the photochemically induced hetero Wolff rearrangement of sulfonylcarbene 11, and (iii) oxygen transfer from ozone to diphenylsulfine 16. Isotopic labeling with C-13 and O-18 allows for the assignment of several characteristic IR vibrations of 5. Irradiation with lambda > 375 nm results in the rearrangement of 5 to 6, which is the first alpha-sultine that has been characterized spectroscopically. The final Product on UV irradiation of 6 is benzophenone (9) and sulfur monoxide.

    The SO2 complexes of scandium, yttrium, and lanthanum difluorides [MF2(O2S)] were prepared via the reactions of laser-ablated metal atoms and SO2F2 upon UV–vis irradiation in cryogenic matrixes. The presence of bidentate SO2 ligand in the products was demonstrated by the characteristic infrared absorptions as well as isotopic frequency ratios from both S18O2F2 and 34SO2F2 experiments and is further

    When mixing SO with O2 in N2, Ne, or Ar, an end-on complex OS–OO forms in the gas phase and can subsequently be trapped at cryogenic temperatures (2.8–15.0 K). Upon infrared light irradiation, OS–OO converts to SO3 and SO2 + O with the concomitant formation of a rare 1,2,3-dioxathiirane 2-oxide, i.e., cyclic OS(O)O. Unexpectedly, the ring-closure of 16OS–18O18O yields a ca. 2 : 1 mixture of cyclic

    On Cu(110)-p(2×1)-O at 300 K SO2(g) reacts stoichiometrically with O(a) to form a surface covered with both c(4×2)-SO3 and p(2×2)-SO3 structures. With heating SO2(g) evolves from the surface in distinct reaction-limited states at 384 K, 425 K, and 470 K, and the surface reverts to its initially oxidized state. On Cu(110), SO2(g) adsorbs molecularly below 300 K; upon annealing to 300 K, the sulfur dioxide

    日期:1993.3
    The 193 nm photodissociation of the isotopomers SO2, SO*2 and SOO* (with O*=18O) was studied by high-resolution photo-fragment translational spectroscopy. The translational energy distributions P(ET) of the fragment pairs SO+O, SO*+O*, SO+O* and SO*+O were determined from systematic analysis of the time-of-flight distributions obtained with various degrees of O* substitution and were found to be significantly

    Infrared spectra of the matrix isolated OMS, OM(η2-SO), and OM(η2-SO)(η2-SO2) (M = Ti, Zr, Hf) molecules were observed following laser-ablated metal atom reactions with SO2 during condensation in solid argon and neon. The assignments for the major vibrational modes were confirmed by appropriate S18O2 and 34SO2 isotopic shifts, and density functional vibrational frequency calculations (B3LYP and BPW91)
