Calculated |A _yyz,as/A_yzy,as| of methyl group as a function of orientation angle θ₀ and angle distribution σ. Here the asymmetric vibrational mode of side chain methyl has the same peak width under different polarization measurements, thus $\left|{\chi }_{\mathit{yyz},as}^{(2)}/{\chi }_{\mathit{yzy},as}^{(2)}\right|=\left|A_{\mathit{yyz},as}/A_{\mathit{yzy},as}\right|$.
