Abstract

The transient dichroic ratio D = delta A parallel/delta A perpendicular has been measured in the visible absorption region of bacteriorhodopsin in purple membrane by a flash photolysis method. D is found to be wavelength independent throughout the visible absorption band, and reaches a maximum value of 2.75 +/- 0.15 on reduction of the excitation intensity. This value is close to that expected for a single nondegenerate transition dipole moment and is incompatible with the strong exciton coupling model used to explain circular dichroism (CD) spectrum of purple membrane. A time-dependent analysis of the exciton interaction and consideration of the coupling strength suggests an explanation of these observations. It is concluded that excitation interaction between retinals in purple membrane is of the weak or very weak type defined by Förster.

摘要

通过闪光光解方法，在紫色膜中细菌视紫红质的可见吸收区域测量了瞬态二向色性比率D = ΔA平行/ΔA垂直。发现D在整个可见吸收带内与波长无关，并且在降低激发强度时达到最大值2.75±0.15。该值接近于单个非简并跃迁偶极矩所预期的值，并且与用于解释紫色膜圆二色性（CD）光谱的强激子耦合模型不相符。对激子相互作用的时间依赖性分析以及对耦合强度的考虑为这些观察结果提供了解释。得出的结论是，紫色膜中视黄醛之间的激发相互作用属于Förster定义的弱或非常弱的类型。
