Why is the CO2-CS2 non-ideality larger than in CO2-CCl4? A Raman scattering study

- Raman spectroscopic study of CO2-CCl4 and CO2-CS2 mixtures at 313 K.
- CO2-CCl4 is found almost ideal and CO2-CS2 strongly non-ideal.
- Nano-segregation without demixing in CS2 concentrated mixtures.
- A diversity of species are present in CO2 concentrated mixtures.
- The connection with the liquid-liquid demixing at lower temperature is discussed.
