Notes:
State-specific ion-molecule reactions of H-atom transfer between the HBr and H2 molecules with HBr+(2Πi,v+) were studied in a free jet flow reactor. The selected spin-orbit and vibrational states of the HBr+ ion were prepared by resonance-enhanced multiphoton ionization. All of the reactant and product ions were monitored using a time-of-flight mass spectrometer. Rate coefficients of the HBr+/H2 reaction vary from 〈2×10−12 cm3/s for the lowest spin-orbit-vibrational state to 2.1×10−11 cm3/s for the highest. Rates for the HBr+/HBr reaction are ∼1.5×10−9 cm3/s independent of the internal state of the ion. © 2001 American Institute of Physics.
