Paper Abstract

This paper concerns with our measurements of reaction center (RC) volume changes in the course of photoactivation using method of holographic interferometry. As a principal value, we studed change of a solution refraction index (Δn) influenced by the sample volume expansion due to temperature changes (ΔnT), light absorption (Δnabs) and changes in the volume of photoactive molecules (Δnv). Using the scheme of temperature compensation we could reduce the task of the case ΔnT << Δnabs, Δn Our estimation for the case of a protein solution yields in relative changes in the molecular volume withing 10-3 + 10-2.
