science-softCon uv/vis+ spectra data base; www.uv-spectra.de; (C) science-softCon 2016 Substance: bromoiodomethane Other Names: iodobromomethane Formula: CH2IBr CAS-No.: 557-68-6 PubChem: Study: photolysis, quantum yields, uv absorption cross sections Authors: C.E. Jones, L.J. Carpenter Title: Solar Photolysis of CH2I2, CH2ICl, and CH2IBr in Water, Saltwater, and Seawater Journal/Source: Environ. Sci. Technol., 39 (16), 6130-6137, (2005); DOI: 10.1021/es050563g Data: table, diagram Energy/Wavelength range: 205 - 365 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: solution (0.5 M NaCl) pH: Comments: The rates and products of the photodissociation of low concentrations of CH2I2, CH2IBr, and CH2ICl in water, saltwater (0.5 M NaCl), and seawater in natural sunlight were determined. Estimated quantum yields for photodissociation were 0.62 ± 0.09, 0.17 ± 0.03, and 0.26 ± 0.06 for CH2I2, CH2IBr, and CH2ICl, respectively, in 0.5 M NaCl, with only small differences from these values in water and seawater.
