Infrared Spectrum of Carbon Trisulfide in Solid Argon

Abstract

Cocondensation of carbon disulfide with high-frequency discharged argon at 4 K produced carbon monosulfide and atomic sulfur, which reacted spontaneously upon annealing to form the carbon trisulfide molecule as identified from the multiplets observed in mixed (12)C, (13)C and (32)S, (34)S isotopic spectra. On the basis of isotopic substitution and theoretical frequency calculations, infrared absorptions at 1263.3 and 570.1 cm(-1) were assigned to predominantly CS stretching and bending vibrations of CS(3) in solid argon. The CS(3) molecule, which was calculated to have a singlet ground state with C(2v) symmetry, dissociated to form the weakly bound SCS-S complex upon visible light irradiation.

Electron Irradiation of Carbon Disulfide-Oxygen Ices: Toward the Formation of Sulfur-Bearing Molecules in Interstellar Ices

“…Here, the experimental results (Figures 3 and 4) suggest that upon electron irradiation, the carbon disulfide (CS 2 ) molecule undergoes unimolecular decomposition to carbon monosulfide (CS) and atomic sulfur (S) (R1). An analogous reaction mechanism was proposed previously to be the primary dissociation channel of carbon disulfide upon microwave discharge and high frequency discharge in an argon matrix (Bohn et al 1992;Ma et al 2009). The dissociation of carbon disulfide (CS 2 ) to both ground state carbon monosulfide, CS(X 1 Σ + ) and atomic sulfur, S( 3 P), is endoergic by 441 kJ mol −1 (4.57 eV) (Table 3).…”

Three-Membered Rings With Two Oxygen and/or Sulfur Atoms

“…As the most likely structure of four possible isomers, dithiirane-2-thione ( 8) was found to be the most stable compound based on computations performed at the MP2 and B3LYP levels of theory. (20) Figure 4…”

Oxygen, sulfur, selenium, tellurium and polonium

“…The IR spectrum of the reactive C 2v -symmetric molecule CS 3 has been recorded in an argon matrix. 10 Adsorption of S onto the Pd (111) surface generates an ordered S over-layer but annealing at 700 K leads to penetration of S into the surface, 11 generating a surface of identical geometry to pristine Pd (111) but with different binding affinities for H 2 . Work by Pore reported the atomic layer deposition of metal selenides and tellurides using alkylsilyl compounds of Se and Te as precursors.…”

“…53 Reaction of Sn[N(SiMe 3 ) 2 ] 2 with 1,2-benzenedithiol (2 : 1 ratio) was reported to form the distannylene (8) which readily decomposed to form (9). In contrast, the reaction of Sn[N(SiMe 3 ) 2 ] 2 with catechol (3 : 2 ratio) gives tri-stannylene (10) which is stable in both solid and solution state. 54 Ab initio studies on the isomers of the cyclic S 2 N 3 + reveal that the experimentally known 1,2-isomer is only kinetically stable, whilst the thermodynamically more stable 1,3-isomer is kinetically unstable with respect to decay to N 2 and SNS + .…”
