摘要：

Common fluorescence properties of carotenoids functioning as an efficient antenna in algal pigment systems are elucidated in relation to their molecular structure. Those carotenoids contain eight conjugated double bonds and one keto group associated with the double bond. The origin of the fluorescence is the optically forbidden S1 state and its radiative lifetime is longer than that of carotenoids without a keto group. These characteristics are discussed in relation to the excited state of polyenes.
