What are we trying to do?

What did we do ?

Just so you know,

1) e.g., experimental data & PGopher analysis for v = 6

2) To obtain “mechanical” information data from these band-by-band results, use conventional spectroscopic expression to generate sets of synthetic pure rotational transition energies

2) To obtain “mechanical” information data from these band-by-band results, use conventional spectroscopic expression to generate sets of synthetic pure rotational transition energies … and a standard regression analysis expression to estimate their uncertainties

This yields,

3) Perform a `Direct-Potential-Fit’ analysis:

Below are the plots of ω0 and dd vs. β0

“ A little disappointment ” .. ???

Results: the most accurate fit to this pure MW PbI data for v=0-6 with re , β1 and β2 free was obtained for β0 = 1.24, and the properties of the resulting potential energy function for levels v=0-11 are shown below:
