UV Induces Formation of CH∙∙∙Cl Hydrogen Bond in Chloromethane

Computational simulations carried out by researchers from the Aix-Marseille University (France), the Federal University of João Pessoa, and the Rural Federal University of Rio de Janeiro (Brazil) showed that the world of the hydrogen bonds may be even more complex than previously thought. They found out that H-bonds can be formed connecting carbon and chlorine atoms in the form of CH∙∙∙Cl bonds. This was discovered when studying the impact of UV radiation on chloromethane (CH3Cl), the most abundant organohalogen in the atmosphere. This work has been recently published in J. Am. Chem. Soc.
