the two biggest H+ <-HBr+(v+) peaks (at 2. 9 and 3 the two biggest H+ <-HBr+(v+) peaks (at 2.9 and 3.38 eV) correspond to v+ (1/2) = 17 for ½ <- ½ and v+(3/2) = 20 for 3/2 <- 3/2 according to calculated v+ levels NB: v+ = 20 for HBr+(3/2) (E =125046 cm-1 ) is very close to v+ = 17 for HBr+*(1/2) (E = 124903 cm-1 ) in energy, (See next slide) -and it closely corresponds to the H + Br+ threshold energy (1249004 cm-1) the biggest peak (at 3.38 eV) corresponds to the v+max for the HBr+ state well. The peak at 2.9 eV corresponds to the accessable v+max for the HBr+* state.
