Particle in a box is a model that is often used to look at the
spectroscopy of pi electrons in conjugated organic molecules.
carotene, a precursor of retinal, a visual pigment found in the
retina of the eye, has the formula given below. -carotene contains
11 conjugated double bonds which contribute 22 electrons that are
delocalized along the length of the molecular chain. Each level of
particle in a box has room for 2 electrons. a. The highest filled
