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 (Δn_T), light absorption (Δn_abs) and changes in the volume of photoactive molecules (Δn_v). Using the scheme of temperature compensation we could reduce the task of the case Δn_T << Δn_abs, Δn Our estimation for the case of a protein solution yields in relative changes in the molecular volume withing 10^-3 + 10^-2.
