1. Calculate for a quantum mechanical system whose angular momentum quantum number has the value 1. Give a numeric answer with correct units.
2. Write down the Hamiltonian for a uranium atom. Use summation notation and give all summation indices explicitly.
3. In the NMR experiment recently carried out in the lab, the rate constant was obtained from the relation

   

   by plotting the quantity on the left-hand side of the equation (call it y) against the delay time t. Suppose that you wanted to add error bars to your graph. You would then need to know , the error in y. Suppose that , (with a negligible error) and compute y and .
