摘 要：The ultraviolet photolysis of CH2I2 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 CH2（OH）2 and HI products. However, photolysis of CH2I2 in salt water leads to formation of new products/intermediates （CH2ICl and Cl2-） not observed in the absence of salt in aqueous solutions. The amount of CH2（OH）2 and HI products appears to decrease after photolysis of CH2I2 in salt water compared to pure water.
