Consider the diatomic molecule HD (composed of a hydrogen atom whose mass is approximately equal to mp and a deuterium whose mass is twice as large) which has a bond length of approximately 0.074 nm
A. What is the moment of inertia of HD (expressed as a number with units)?
B. What is the value of the quantum number J, and the degeneracy, of the rotational quantum state of HD whose energy is 3h2/I ?
C. What is the root-mean-squared magnitude of the angular momentum of HD in the same rotational state as in part b?
D. What are all the possible expectation values of the projection of the angular momentum of HD along the z-axis when it is in its second excited rotational state (two-levels above the ground state)?
E. What frequency of light (expressed in cm excite HD from its ground to its first excited rotation state? units) would be required to
