T1 - Molecular Model for Critical Opalescence of Carbon Dioxide
AU - Chaikina, Yu.A.
AB - Under the experimental fact that CO₂ critical density variance is small, a molecular model for critical CO₂ is formulated. Based on it, a Rayleigh light scattering descri ption is developed. The suggested formula for the critical scattering differs from the Ornstein— Zernike equation in terms of a more complicated angle and correlation length dependences. The described scattering possesses essential features of the critical opalescence. For the first time the influence of molecular thermal motions onto the critical Rayleigh light scattering is explicitly accounted.
