一般描述
Bromoform is a major organic source for atmospheric reactive bromine BrOx (Br+BrO). It is formed as a product of chlorination of drinking water. It undergoes photodissociation to form the Br2 fragment and mechanism has been investigated by cavity ring-down absorption spectroscopy.
应用
Bromoform was used to evaluate the genotoxicity of chlorodibromomethane, bromodichloromethane and bromoform.

Chlorination of drinking water results in the formation of chlorodibromomethane, bromodichloromethane and bromoform. These trihalomethanes have all shown evidence of genotoxicity in bacterial and mammalian cell systems in vitro and some evidence of carcinogenicity in rodents. Chlorodibromomethane and bromodichloromethane have

Iso-polyhalomethanes are known reactive intermediates that play a pivotal role in the photochemistry of halomethanes in condensed phases. In this work, iso-bromoform (iso-CHBr(3)) and its deuterated isotopomer were characterized by matrix isolation infrared and UV/visible spectroscopy, supported by ab initio
