The π electrons of a conjugated molecule can be modeled as a particle in a box where the box length is a little more than the length of the conjugated chain. The Pauli exclusion principle permits no more than two electrons to occupy every energy state. For a conjugated hydrocarbon chain molecule with three double bonds (CH2=CH-CH=CH-CH=CH2), determine the wavelength of radiation absorbed when the π electron is excited from the highest-occupied state to the lowest vacant state.
