HCl Vibrational-Rotational Spectroscopy

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.

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 B_e and alpha_e (Eq, 19)

5) Solve for "r" the average internuclear separation.
