The REMPI spectra of o-, m- and p-bromofluorobenzene and the photodissociation of p-bromofluorobenzene

► The REMPI spectra of o-, m- and p-bromofluorobenzene in the S1 state were studied. ► The band origin was influenced by resonance effect and inductive effect. ► The molecular geometry in the S1 state is not as rigid as in the S0 state. ► The potential barrier height of p-BrFPh is determined approximately.
