Abstract

The ultraviolet photolysis of polyhalomethanes such as CH2I2in water was investigated. The gas and solution pa\hse picosecond time-resolved resonance Raman spectroscopy was used for the study. It was observed that ultraviolet photolysis of CH2I2led to almost complete conversion into CH2(OH)2and 2HI products. It was also found that the photolysis at low concentration led to efficient dehalogenation as well as release of multiple strong acid (HI) leaving groups.
