Question

n this problem you will determine the wavelength of the photon required to excite a conjugated linear molecule, like butadiene only with 42 carbon atoms instead of 4. Assuming that this molecule is linear and has an alternating arrangement of double and single bonds where the bonds between the far left and right carbon atoms with their neighbours are double bonds, determine the length of the molecule. (State your answer in meters, use scientific notation X.XXE-XX)

What is the energy required to promote an electron from the highest occupied energy level to the lowest unoccupied energy level in this molecule? State your answer in Joules, and use scientific notation (X.XXE-XX)

What is the wavelength of the photon required to cause this transition to occur? (in meters, use scientific notation X.XXE-XX)
