Problem- The lowest electronic transition frequently corresponds to an electron in the highest occupied molecular orbital" or HOMO absorbing a photon and moving to the "lowest unoccupied molecular orbital", or LUMO. Using the particle in-a box model for linear conjugated "pi" systems, estimate the wavelength of light, , necessary to promote an electron from the HOMO to LUMO levels for: 1,3 butadiene and 1,3,5hexa-triene.
