Figure 4

Variation of isotropic and anisotropic Raman peak frequencies of C=O stretching mode of γ-Caprolactone as a function of solute volume fractions (C6H10O2 + CCl4). The curves were fitted with negative exponential functions [anisotropic: ƒ(x) = 9.11e −7.27x + 1769.96, r 2 = 0.9734; isotropic: ƒ(x) = 16.26e −5.65x + 1762.42, r 2 = 0.9899].
