Abstract

Rayleigh scattering expressed with formalism of depolarized and polarized components offers possibilites for analysis of optical molecular anisotropy for liquid materials (pure, diluted solutions with large and small molecules). Various devices exist for measuring scattering, but with laser systems for static scattering enough data is collected. With the use of laboratory type He Ne lasers with basic transition at 632.8nm, scattering of organic solvents was measured, characteristic for calibration. These measurements served for materials feature comparison acquired with spontaneous sources and quantum generators - lasers. Based on assessment, the measurements of less known materials were evaluated which are of interest for biological processes (phytol and related compounds) for gaining in site into behaviour of phytil group).
