Careful analysis of CARS-spectroscopy data for carbon dioxide Fermi-dyad shows that critical density variance must not exceed 0.4 and the lifetime of critical density fluctuations is not less than 10 ns. To comprehend the experimental data, the contribution of critical fluctuations to the spectral line width is evaluated taking into consideration their lifetime.
