Taking into consideration the fact that the variance of the density of critical CO2 is small, a molecular model of critical CO2 is formulated for the first time. Based on it, the intensity of Rayleigh light scattering is calculated. The expression fo

Detailed analysis of CARS-spectroscopy experimental data of the carbon dioxide Fermi dyad showed that critical density variance should not exceed 0.1 and the lifetime of critical fluctuations is more than 10 ns. To interpret the experimental data, an

Data on coherent anti-Stokes Raman scattering (CARS) spectroscopy of supercritical CO2 are analyzed by methods of statistical theory. The following is shown. The random local structure of supercritical CO2 is laminated at the critical density and a t

Equations for large-scale local fluctuations in fluids, from an ideal gas to an incompressible fluid, including the critical and supercritical state are derived for the first time based on the first principles. The modern phenomenological representat

The contribution of local medium fluctuations to the rates of thermal chemical reactions was calculated for the first time. It was shown for the “ideal gas” model that the fluctuation contribution to a rate constant was proportional to the specif

Rate constants for electron-vibrational energy exchange Ar(3 P 2) + N2(X 1Σ + , ν = 0) → Ar(1 S 0) + N2(C 3Π u , ν′), where ν′ = 0, 1, 2, were calculated. Calculations were performed taking into account the presence of a resonance in elect

The rate constant for the quenching of excited F(2P1/2) and Cl(2P1/2) atoms in collisions with N2 molecules were calculated. The electron interaction matrix between N2(X1Σg+) and F and Cl atoms in the 2Pj state calculated asymptotically taking into
