Femtosecond photolysis of CH2Br2 in acetonitrile: Capturing the bromomethyl radical and bromine-atom charge transfer complex through deep-to-near UV probing

► CH2Br2 in acetonitrile is a suitable precursor for radical species and their absorption bands. ► We record the UV absorption spectra of the CH2Br radical in acetonitrile and methylcyclohexane. ► The absorption of the CH3CN·Br charge-transfer complex is also recorded. ► Recording these spectra is made possible due to the ultrafast decay of the iso-CH2BrBr product.
