Adapted from Experiment #38 (Shoemaker, Garland, Nibler, 1989)
1) Sample preparation
2) IR Gas-phase data collection --> here is some data, if you did not get it in lab.
3) Spectrum analysis including analysis of state populations.
- 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) Plot "m" (x) vs the frequency (y) and fit to a second order polynomial.
5) The second order polynomial will take the form of equation 9 from (Exp 38, Shoemaker), hence you can determine alphae, and then of Be.
6) Using equation 5 and 3, then solve for "r" the average internuclear separation.
