Abstract

The vibrations of o-, m- and p-bromofluorobenzene (BrFPh) in the first electronically excited state are studied by (1 + 1) resonance-enhanced two-photon ionization spectroscopy. The observed vibrational bands have been assigned on the basis of comparison with the results from theoretical calculations. The band origins of the S ₁ ← S ₀ electronic transitions of o-, m- and p-BrFPh, which were influenced by positive resonance effect and negative inductive effect, are found to be 36986.68 cm ^-1, 36961.48 cm ^-1 and 36223.20 cm ^-1 respectively. Meanwhile, the potential barrier height (the energy of the crossing points between the bound S ₁ state and a repulsive state relative to the S ₁ minimum) of p-BrFPh is determined to be lower than 2815 cm ^-1 (0.3490 eV) by the REMPI spectra of bromine atom and p-BrFPh molecule.
