Plastic photochromic sunglasses are based on the following reversible rearrangement of a dye inside the lenses that occurs when the lenses are exposed to sunlight. The original dye absorbs UV light but not visible light and is thus colorless, while the rearrangement product absorbs visible light and is thus darkened. (a) Show the mechanism of the rearrangement. (b) Why does the rearrangement product absorb at a longer wavelength (visible light) than the original dye (UV)?

Draw the mechanism.
