Low‐frequency Raman spectra of liquids on both Stokes and anti‐Stokes sides were investigated. The spectra are given in the R (v̄) representation. Results for a pure and an impure sample of fluorobenzene were compared. The results allow a distinction between the effects of stray light and fluorescence in the spectra. The same method was used for liquid water at temperatures ranging from the freezing point to 40°C. The background correction for Raman spectra in the R (v̄) representation is discussed. This procedure is of special importance for aqueous solutions of biologically interesting molecules. The use of the anti‐Stokes side is an advantage, as demonstrated by R (v̄) spectra of an aqueous solution of L‐aspartic acid.
