The photodissociation of C3 H7 Br is investigated by spin-orbit ab initio calculation method. The vertical excitation energies of some excited states for C3 H7 Br are calculated. The potential energy curves of C3 H7 Br along the C - Br dissociation coordinate are calculated by multistate second order multi-configuration perturbation theory in conjunction with spin-orbit interaction through complete active space state interaction( MS-CASPT2 / CASSI-SO). The photodissociation channels observed experimentally leading to C3 H7 + Br(2 P3 / 2 )and C3 H7 + Br*( 2 P1 / 2 )are assigned on the basis of this work.
