1) Calculate the moment of inertia of the molecule NO, which has an equilibrium bond length of 1.151x10-10m.

2) The internuclear distance for the diatomic molecule NO is 1.151x10-10m. Determine the values of its first three rotational energy levels.

3) HCl gas absorbs radiation that has wave numbers of 20.7, 41.5, 62.3, 83.0, 103.8 cm1 . Determine the bond length for HCl.

4) The rotational spectrum of 79Br19F shows a series of equidistant lines spaced 0.71433cm-1 apart. Calculate the rotational constant B, and hence the moment of inertia and the bond length of the molecule.

5) The diatomic molecule HCl has a B constant of 10.593cm-1 and a centrifugal distortion constant D of 5.3x10-4 cm-1 . Estimate the vibrational frequency and the force constant of the molecule. The observed vibrational frequency is 2991cm-1 . Explain the discrepancy.
