Time courses of light-induced absorption changes of carotenoid (spheroidene) in chromatophores of the photosynthetic bacterium, Rhodopseudomonas spheroides, consisting of an 8-10 nm-shift in the carotenoid absorption spectrum towards the longer wave-length, were investigated. The whole time course of absorption change can be expressed as the sum of two first order reactions; a rapid change accomplished in several msec after the onset of illumination with actinic light (800-900 nm) and a slow change extending over the whole period (200 msec). The rapid change required a high light intensity, whereas the slow change was saturated at relatively low light intensity (ca. 5×10^3 erg/cm^2 sec). Electron transport inhibitors (HOQNO, piericidin A and o-phenanthroline) and Cl-CCP, at concentrations uncoupling photophosphorylation (10^<-6> M), inhibited slow change but did not affect rapid change. The rapid change was inhibited by higher concentrations of Cl-CCP (10^<-4> M) and by o-phenanthroline in the concomitant presence of an uncoupling concentration of Cl-CCP. The rapid and slow changes have midpoint potentials of 440 and 420 mv, respectively; as calculated from absorption changes in the presence of ferri- and ferrocyanide mixtures. Relationships between absorption spectrum changes and other reactions in the chromatophores were analyzed. Slow absorption change is closely related to the high energy intermediate, or state, of photophosphorylation. Rapid absorption change, with a midpoint potential of 440 mv, is related to the electron flow mediated by P870; although it does not directly reflect the state of P870, itself.
