“…Sulfur chemistry has been attracting the attention of researchers in the fields of space and atmosphere. Isotopic abundance of 13 C 32 S and 12 C 34 S in the interstellar medium was measured to investigate the source-to-source variation of 12 C and 13 C in space. 1 Radicals containing sulfur atoms (CS, SO, and S 2 ) generated from CS 2 have been thought to be precursors of sulfuric acid aerosol in the stratosphere.…”

The internal energy distributions of reaction products are important information in clarifying the mechanism of chemical reactions. There are few reports of the nascent vibrational energy distribution of CS(X 1 Σ + ) generated in the S( 1 D) + CS 2 reaction. As long as S( 1 D) is produced by photodissociation of CS 2 , CS(X 1 Σ + ), as a product of the chemical reaction and as a photoproduct of CS 2 is indistinguishable. In this study, S( 1 D) was generated by the photolysis of OCS at 248 nm, where CS 2 hardly dissociates, and CS(X 1 Σ + ) was generated only by the S( 1 D) + CS 2 reaction. The vibrational levels v″ = 0−6 of CS(X 1 Σ + ) were detected with laser-induced fluorescence (LIF) via the A 1 Π−X 1 Σ + transition. The identical time profiles of the LIF intensities showed that all the vibrational levels were produced by the S( 1 D) + CS 2 reaction. The relative nascent vibrational populations of CS(X 1 Σ + ) determined from the area intensities of the excitation spectra are 1.00 ± 0.
