Photodissociation of CH₂BrCl was investigated around 265 nm using resonance-enhanced multiphoton ionization technique combined with velocity map ion-imaging detection. The ion images of Br (²P_1/2) and Br (²P_3/2) were analyzed to obtain the corresponding velocity distributions and total translational energy distributions. Using an impulsive model invoking angular momentum conservation, the vibrational internal energy distributions of chloromethyl radical (·CH₂Cl) formed by the photodissociation of CH₂BrCl, were derived from the total translational energy distributions. In the CH₂BrCl+hv→Br (²P_1/2)+CH₂Cl channel, v₄, v₃+v₄, v₂+v₄ and v₂+v₆ vibrational modes were found to be excited in the radical; while in the CH₂BrCl+hv→ Br (²P_3/2)+CH₂Cl channel, the excited vibrational modes were v₂+v₆, v₁+v₃, v₂+v₅, v₂+v₃+v₅, and v₁+v₅. The results further implied that, following absorption of one photon by the parent molecule CH₂BrCl, other vibrational modes besides v₅ (CBr stretch) mode, such as v₇ (CH₂ a-stretch) mode, are excited in the parent molecule.
