1. 1,3,5,7-Cyclooctratetraene (C8H8) is a conjugated 8-member carbon ring with a diameter of 3.667 . This molecule can be treated accurately using a model that considers the electrons as particles confined to the carbon ring of the molecule. Using this model answer the following questions.

f. What is the energy and angular momentum of an electron in the highest occupied state?

g. What wavelength of light can induce a transition from the highest occupied to the lowest unoccupied state?

h. Can you see a photon of this wavelength?

i. Suppose that 1,3,5,7-Cyclooctratetraene were the chromophore in human eyes rather than retinal. What would the radius of electron delocalization for this molecule when bound to a rhodopsin type protein need to be in order for absorbance to occur at 540 nm?

j. Assuming that one 1,3,5,7-Cyclooctratetraene molecule is excited for each photon, how many molecules are excited when a sample is exposed to a 100 W, 540 nm source for 100 msec?
