Real Diatomic Molecules Temperature Spectrum of Nitrogen Isotopic Substitution Nuclear Spin Statistics Predict the Spectrum of Oxygen   Further investigation of the interaction of the nuclei can be use to identify the molecule from the spectrum. Launch Applet 6. The applet shows the spectrum of a diatomic . Q8.1 Is a Boson or a Fermion? Justify your answer. Q8.2 Calculate the degeneracy and Boltzman factor of the first 7 rotational levels Q8.3 By dividing the intensity of the first 4 Anti-Stokes transitions by the degeneracy and the Boltzman factor for that transition work out the nuclei spin statistical weight for . Q8.4 Given that the Y-Y bond length is 198.75pm calculate the mass of the nucleus and hence the identity of atom Y.     << previous page www.physchem.ox.ac.uk next page >>
