Adapted from Experiment #38 (Shoemaker, Garland, Nibler, 1989)
1) Sample preparation
2) IR Gas-phase data collection
3) Spectrum analysis including analysis of state populations.
https://en.wikipedia.org/wiki/Isotopes_of_chlorine atomic masses in amu
Reduced mass, "mu" = (m1*m2)/(m1+m2)
1H 1.007825 amu (99.9885%)
35Cl 34.968853 amu (75.78%)
37Cl 36.965903 amu (24.22%)
conversion factor: 1.66054e-27 kg/amu
4) Determination of Be and alphae (Eq, 19)
5) Solve for "r" the average internuclear separation.
