1 HBr 6pp.. vs. V(m+17) state interactions

4 https://notendur.hi.is/agust/rannsoknir/papers/jcp93-4624-90.pdf:
From Q lines DE(J´,J´-1) This differs a lot from Longs Results (Why?):

5 https://notendur.hi.is/agust/rannsoknir/papers/jcp93-4624-90.pdf:

6 Is this peak split? Are these J´= 0 and 1 peaks In which case J´=8
Br Atomic Line? ?

7 DE(J´,J´-1) !! J´ It could be that there are two peaks
It could be that there are two peaks In this are in which case j’ increases by one In which case the highest J´observed is indeed J´=8 But not J´=7(?) DE(J´,J´-1) !!

J 6pp V(m+17) V(m+18) E(n=6) 1 2 3 4 5 6 7 8 9 ref: C&G "Tables" dropbox 250512

9 V1S+(v´=m+18) : Energy / cm-1 Near-reonance Interaction J´
E1S+(n=6; v´=0) 8 8 7 Off-reonance Interactions 2 V1S+(v´=m+17) 6pp3S-(v´=0) and PPT file for Fig.4 in HBr-New States-paper

10 DnJ,J+1 = 2(B´-B´´)J´ + 2(B´-B´´) for Q lines
: DnJ,J+1 = 2(B´-B´´)J´ + 2(B´-B´´) for Q lines a = b (slope = intersect)

11 a(intersect)= = -15.145 ± 4.46 b(slope) = -11.788 ± 1.24 i.e. for J´=0

12 This is what one expected to give closes a and b values
Skip top and bottom points

13 This is what one expected to give closes a and b values

14 Closest values for slope and intersect ERGO: J´min = 3, J+1 =4!
b = ± 1.01 Closest values for slope and intersect ERGO: J´min = 3, J+1 =4! a = ± 6.25 b = ± 1.01

15 Large variation in the match of “a” and “b” depending on what peaks are taken
account of. ERGO: comparing “a” and “b” is NOT useful tool to use for Assignment in this case (as might be expected)
