The ultraviolet photolysis of CH_2I_2 was studied in water [1-3] and salt water solutions using photochemistry and picosecond time-resolved resonance Raman spectroscopy. Photolysis in both types environments produces mainly CH_2(OH)_2 and HI products. However, photolysis of CH_2I_2 in salt water leads to formation of new products/intermediates (CH_2ICl and Cl_2-) not observed in the absence of salt in aqueous solutions. The amount of CH_2(OH)_2 and HI products appears to decrease after photolysis of CH_2I_2 in salt water compared to pure water.
