6. 1) NB!: contributions from v´ 21 CLEARLY CAN NOT BE IGNORED!!! This analysis assumes W 12 to be constant and independent with v´(ip) and to be the same value as that derived from shift analysis for v´(ip)=21.  and  are also assumed to be constant and independent with v´(ip) : Thus least square analyses on  and  (for W 12 = 25 cm -1 ) resulted in W 12 = 25 cm -1  = 2.5  = 0.0124 for j(0 + ) H35Cl The significantly larger  value, compared to that observed for other triplet states (  = 0.002 – 0.004) might be because of a large contribution to the dissocaiation Channels from photodissociation follwed by Cl ionization, i.e. 2hv + HCl ->-> HCl*(j(0 + ),v´=0, J´) HCl*(j(0 + ),v´=0, J´) + hv -> HCl** -> H + Cl* Cl* + hv -> Cl + + e - Analogous analysis now need to be done for H 37 Cl!!!!!

7. The J’ = 6 peak is problematic for H35Cl since the mass peaks for J’ = 6 and 8 overlap. Hence the experimentally evaluated ion ratio for J’ = 6 will be an underestimated value. Therefore it is acceptable that the calculated ratio is higher. This should not be the problem for H37Cl. Lets try to include v´=18 and 23 interactions:

9. It is interesting to see that the contribution falls down very slowly as  E(J´) increases / v´ “moves further away” from the Rydberg state. But what happens if W 12 changes with v´, say W 12 increases? I tried 1)W 12 = 22,23,24,25,26,27 vs v´=18,19,20,21,22,23 & 2)W 12 = 19,21,23,25,27,29 vs v´=18,19,20,21,22,23 & 3)W 12 = 28,27,26,25,24,23 vs v´=18,19,20,21,22,23 & 4)W 12 = 31,29,27,25,23,21 vs v´=18,19,20,21,22,23  No big change  Looking at calculations such as in the previous figure shows that contribution from v´ 21 is close to a constant (  ). Therefore the relevant expression for I(Cl+)/I(HCl+) is Is it perhaps possible to obtain good fit for the parameters  and  only assuming  to be zero?

10. No that does not seem to be the case. In other words gamma is an important parameter. Looking at: It is clear that c 2 2 is very small and the ratio for v´ 21 is simply: NB! It is interesting to see that similar  values are obtained independet of the number of v´(V) contribution:  = 0.013 for v´=20-21 (KM)  = 0.0124 for v´= 19-22  = 0.0135 for v´= 18-23 THIS IS IMPORTANT!

11. Effect of  is clearly seen below:

12. W 12 = 25,  = 1.7  = 0  = 0.006  = 0.013 v´=18,19,20,21,22,23 and sum J´ agust,heima,...Jan11/Evaluation of coupling strength j state-220111kmak.xls How can I make the colors in the excel graph to stay unchanged?

13. W 12 =25, f = 1 Minimize with respect to  and  =>  = 2.2,  = 0.0198, least sq. error(J´=0-5) = 0.000706 agust,heima,...Jan11/Evaluation of coupling strength j state-220111kmak.xls J´ NB!: As a rough estimate I increased The experimental Ratio value to 0.5 We realy need to analogous test on H37Cl where the peak overlap problem does not exist.

14. Lets´ compare the calc. sum values for different optimizaed  values: Is the graph shape perhaps comparable?: Lets look at plots normalized to the largest peak (i.e. J´=6) See note from 230111: ** least sq.(0-6)(rel) 0.0130.03710.002602391 0.0090.04460.002591518 0.0050.05260.002591518 00.062590.002591521 f (in f*  *  ) 0.0132.8160.002591523 0.0094.9540.002591524 0.00318.860.002591532 f (in f*  *  ) All same! 0.0312900.002591532 All same! agust,heima,...Jan11/Evaluation of coupling strength j state-230111kmak.xls Fit of I rel (exp) = (I(Cl + )/I(HCl + )(J´;exp))/(I(Cl + )/I(HCl + )(J´ max ;exp)) vs J´ by I rel (calc)= (I(Cl + )/I(HCl + )(J´;calc))/(I(Cl + )/I(HCl + )(J´ max ;calc)) vs J´ NB!: J´ max = 6 All give equally good fit (see figure next slide) ERGO: 1) Use f = 0 (i.e. Neglect f*  *  ) 2) Use only v´= 20 & 21 and perform fit on I rel (exp) vs J´ by varying  only!!! Thus the  parameter drops out
