Calculate the ground state energy of of pi-electrons in octatetraene, C8H10, using the particle in a box model. To calculate the box length, assume that the molecule is linear and use the values 1.35 and 1.54 angstroms for C=C and C-C bonds. What is the minimum energy and corresponding wavelength of light required to induce an electronic transition in this molecule?
