Explore the complexities of J´ states in HBr spectroscopy, uncovering peak splits and peak identities while examining the energy interactions between different states. Discover potential variations in absorption peaks and the challenges of matching slope and intersect values.

Is this peak split? Are these J´= 0 and 1 peaks In which case J´=8 Is this Br Atomic Line? ? https://notendur.hi.is/agust/rannsoknir/rempi/hbr/Jan12/PXP-240512aka.pxp
https://notendur.hi.is/agust/rannsoknir/rempi/hbr/Jan12/XLS-240512aka.xls: 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(?)

a(intersect)= = -15.145 ± 4.46 b(slope) = -11.788 ± 1.24 i.e. for J´=0 J´+1 = 1 ! J´ a = -3.3571 ± 5.53 b = -11.788 ± 1.24 J´ https://notendur.hi.is/agust/rannsoknir/rempi/hbr/Jan12/PXP-240512akb.pxp
a = 8.4307 ± 6.66 b = -11.788 ± 1.24 This is what one expected to give closes a and b values Skip top and bottom points https://notendur.hi.is/agust/rannsoknir/rempi/hbr/Jan12/PXP-240512akb.pxp
a = -25.886 ± 3.36 b = -8.43 ± 1.01 a = -17.456 ± 4.3 b = -8.43 ± 1.01 This is what one expected to give closes a and b values https://notendur.hi.is/agust/rannsoknir/rempi/hbr/Jan12/PXP-240512akb.pxp
a = -9.026 ± 5.27 b = -8.43 ± 1.01 Closest values for slope and intersect ERGO: J´min = 3, J+1 =4! a = -0.596 ± 6.25 b = -8.43 ± 1.01 https://notendur.hi.is/agust/rannsoknir/rempi/hbr/Jan12/PXP-240512akb.pxp
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)
