**Unformatted text preview: **a and b , where b = 2 a . Write down the quantum numbers corresponding to the ﬁrst 5 energy levels of this system. Note any degeneracies. Problem 3 – particle on a ring The π electrons in benzene can be approximated as particles on a ring. Calculate the diameter of this “electron ring” if it is assumed that a transition occurring at 260.0 nm corresponds to an electron going from n = 3 to n = 4. Compare this diameter to the diameter of a benzene molecule, if you approximate the carbon hexagon with a circle. Problem 4 Do problem P15.32 from the course textbook. 1...
