N2 - Mass spectra were recorded for (2 + n) REMPI of CF3Br as a function of resonance excitation energy in the 71 320-84 600 cm-1 region to obtain two-dimensional REMPI data. CF3+, iBr+ (i = 79,81) and C+ ions were detected. Laser power dependence experiments were performed for ion signals. CF3+ signals due to resonance transitions from the ground state CF3Br to number of Rydberg states and various vibrational states followed by CF3+ and Br- ion-pair formation via intersystem crossings, were identified. Bromine atom production by predissociation channels via two-photon excitation to the Rydberg states is proposed, based on detecting bromine atom (2 + 1) REMPI.
