Abstract
- The relative absorption spectrum of the pigments in their natural state in the photosynthetic bacterium Spirillum rubrum is given from 400 to 900 mmicro. The position of the absorption maxima in the live bacteria due to each of the pigments is: green pigment, 420, 590, 880; red pigment, 490, 510, 550. 2. The relative absorption spectrum of the green pigment in methyl alcohol has been determined from 400 to 900 mmicro. Bands at 410, 605, and 770 mmicro were found. 3. The wave length sensitivity curve of the photosynthetic mechanism has been determined and shows maxima at 590 and about 900 mmicro. 4. It is concluded that the green bacteriochlorophyll alone and not the red pigment can act as a light absorber for photochemical CO(2) reduction.
摘要
给出了光合细菌红螺菌中色素在其天然状态下的相对吸收光谱，范围从 400 到 900nmicro。每种色素在活细菌中吸收最大值的位置是：绿色素，420、590、880；红色素，490、510、550。
已经从 400 到 900nmicro 确定了甲醇中绿色素的相对吸收光谱。发现了 410、605 和 770nmicro 处的带。
已经确定了光合作用机制的波长灵敏度曲线，在 590 和大约 900nmicro 处显示出最大值。
可以得出结论，只有绿色细菌叶绿素而不是红色素可以作为光吸收剂进行光化学 CO2 还原。
