Raman spectra of liquid carbon disulfide (CS2) were measured under high pressures and in dilution with ethanol and with heptane. The pressure and concentration dependences of the molecular vibration modes 1 and 2 2 of CS2 are discussed. The intermolecular distance changes simultaneously with concentration and pressure. In addition, dilution also varies the environment around the CS2 molecule. The derivative of the intermolecular interaction energy is obtained from the frequency shift from the gas phase to the liquid phase of the 1 and 2 2 vibrations. The results show that dilution effectively acts as negative pressures, where the intermolecular distance between CS2 molecules increases in the mixtures with ethanol and heptane. These effective pressures and pressures give the change in the intramolecular double bond between carbon and sulfur atoms. But, these give a different effect for the damping of vibrations.
