Vaghjiani Title: CH3SH ultraviolet absorption cross sections in the region 192.5-309.5 nm and photodecomposition at 222 and 193 nm and 296 K Journal/Source: J. Chem. Phys., 99, 5936-5943, (1993); DOI:10.1063/1.465917 Data: table, diagram Energy/Wavelength range: 192.5 - 309.5 nm Resolution: 0.25 - 1.10 nm Temperature: 296 K Temperature dependence: no Pressure/Concentration: Phase: vapor pH: Comments: The primary quantum yields of H atom produced in the 222 nm and 193 nm laser photolysis of CH3SH have been determined to be 0.95±0.10 and 0.49±0.08 relative to 248 nm CH3SH photolysis and 193 nm HBr photolysis, respectively, at 296 K.
