Phys. 369, Fall 2009 Homework #5 Due: Weds. Oct 7, beginning of class 100 points total 1. (12 points) Suppose that an oxygen molecule is a spin-1/2 particle with a magnetic moment of 2 Bohr magnetons. (It’s actually not, but just pretend). Using the theory of paramagnetism developed in Schroeder chapter 3, calculate the magnetic susceptibility of oxygen gas at room temperature and atmospheric pressure. Compare your result to the experimental value quoted in Table I of the notes. 2. (12 points) Find a copy of the CRC Handbook of physics and chemistry. One place is the reference section of the PMA library. a) The handbook contains a table of the magnetic susceptibility of organic compounds. Look up this table. How common is paramagnetism in organic compounds? How common is diamagnetism? What does this tell you about how frequently electrons are paired in organic

How common is diamagnetism? What does this tell you about how frequently electrons are paired in inorganic compounds? c) In the table for inorganic compounds, you will notice that some have very high susceptibilities. What do these compounds have in common? Why is their susceptibility not suppressed down to a low level by electron pairing? 3. (16 points) Schroeder, problem 3.18 4.
