The orientational change of the absorbing dipole of the retinal chromophore in vertebrate rhodopsin (rhodo) upon photo-excitation to bathorhodopsin (batho), lumirhodopsin (lumi) and isorhodopsin (iso), has been studied by polarized absorption and lin

We have used electron microscopy and model calculations to analyze the physical basis of light-scattering signals from suspensions of photoreceptor membranes. These signals have previously been used to probe interactions between photoactivated rhodop

Orientation angles of five emitting dipoles of chlorophyll a in thylakoids were estimated from low temperature fluorescence polarization ratio spectra of magnetically oriented chloroplasts. A simple expression is given also for the evaluation of data

The perturbation theory provides an explanation of the trans-membrane electric field effects on the polarizability of the photosynthetic pigments. In the photosynthetic membranes, the photo-induced effect is linear despite the spectroscopic propertie

A calculation using the dipolar approximation provides the fluorescence polarization values for chloroplasts in every geometrical situation. The orientation of the concerned pigments with respect to the photosynthetic membranes is taken into account.

In rod outer segments, photoexcited rhodopsin (R*) activates a cyclic GMP phosphodiesterase through a sequence of reactions involving a GTP-binding protein. By measuring light-scattering changes above 700 nm, we have studied the kinetics and stoichio

In order to investigate the state of pigments in vivo and particularly their orientation, we needed some physical model where the pigments are oriented. Study upon stretched films containing chlorophylls has been done using a sensitive LD measurement
