I. Weak „near resonance“ interactions of the Rydberg states with ion-pair(V) states:a) F1D2(v´=1) with V(m + 7) ANDb) k3P1(v´=0) with V(m + 9)

See:https://notendur.hi.is/agust/rannsoknir/papers/HBr/jcp136-214315-12.pdfhttps://notendur.hi.is/~agust/rannsoknir/papers/HBr/jms282-20-12.pdf

II. Medium to strong „off-resonance“ interactions of the Rydberg states :a) H1S+(v´=0)b) E1S+(v´=1)-with V(m+7), V(m+8), V(m+9)

For example

ERGO: Detect H, Br, H* and Br* by 2nd color, i.e.

H(n=1) + 2hn -> H*(n=2) …..+hn -> H+ + e: 2hn = 82 258.95 cm-1 / hn= 41129.48 cm-1 / l =243.1346 nmH*(n=2) + hn -> H*(n=3) …….+hn -> H+ + e: hn = 15233.15 cm-1 / l = 656.463 nm

Br = Br(3/2) & (1/2); Br* = Bromine Rydberg states, for example https://notendur.hi.is/agust/rannsoknir/rempi/cf3br/Thesis-Kari-jan11.pdf , page 12 :
