Energy transfer between carotenoid and bacteriochlorophyll has been studied in isolated B-800-850 antenna pigment-protein complexes from different strains of Rhodopseudomonas sphaeroides which contain different types of carotenoid. Singlet-singlet energy transfer from the carotenoid to the bacteriochlorophyll is efficient (75-100%) and is rather insensitive to carotenoid type, over the range of carotenoids tested. The yield of carotenoid triplets is low (2-15%) but this arises from a low yield of bacteriochlorophyll triplet formation rather than from an inefficient triplet-triplet exchange reaction. The rate of the triplet-triplet exchange reaction between the bacteriochlorophyll and the carotenoid is fast (Ktt greater than or equal to 1.4 . 10(8) S-1) and also relatively independent of the type of carotenoid present.
在来自不同球形红假单胞菌菌株的分离的B-800-850天线色素-蛋白质复合物中，研究了类胡萝卜素与细菌叶绿素之间的能量转移，这些复合物含有不同类型的类胡萝卜素。在测试的类胡萝卜素范围内，从类胡萝卜素到细菌叶绿素的单重态-单重态能量转移是高效的（75%-100%），并且对类胡萝卜素类型相当不敏感。类胡萝卜素三重态的产率较低（2%-15%），但这是由于细菌叶绿素三重态形成的产率较低，而不是由于三重态-三重态交换反应效率低下。细菌叶绿素与类胡萝卜素之间的三重态-三重态交换反应速率很快（Ktt大于或等于1.4×10⁸ S⁻¹），并且也相对独立于所存在的类胡萝卜素类型。
