Coronene is a planar molecule with 18 conjugated carbon atoms, disposed on a circle of 0.84 nm. a) Draw the energy levels for the first 11 orbitals (huckle rule) in coronene and indicate the quantum number m for each of them. b) Use the particle on the ring model to calculate the wavelength of the excitation of coronene from m = 4 to m = 5. c) Upon heating, the diameter of coronene increases by 2%, how does this affect the transition energy?
