The intense color of carotenoids is caused by the strong extinction in the region, 400–500 mμ, where the spectral curve shows a massive band. If the latter exhibits vibrational fine structure, in most instances three maxima or two maxima and a shoulder appear, whereby the middle peak has the highest intensity.
