  • Raman spectrum of CF4 in liquid-argon solution -

    1974-12-1RESULTS AND DISCUSSION Raman spectra of CF4 in liquid Ar were measured at concentrations of 10, 1, and 0.26 %. The spectrum of the 0.25 % solution is shown in Fig. 1, where it is compared with those of the pure liquid and the gas. In the spectra of the liquid and the solution the bands are much sharper than those in the spectrum of the gas.
