When ß-carotene is oxidised in vivo, it breaks in half and forms two molecules of retinal (vitamin A), which is a precursor to the pigment in the retina responsible for vision. The conjugated system of retinal consists of eleven C atoms and one O atom; see the structure of the molecule here: H3C CH3 CH3 CH3 `H CH3 In the ground state of retinal, each level up to n = 6 is occupied by two electrons. Assuming an average inter-nuclear distance of 140 pm, use the particle-in-a-box model to calculate: a. the separation in energy between the ground state and first excited state in which one electron occupies the state with n = 7, and b. the frequency of the radiation required to produce a transition between these two states.
