摘要：

Comparison between low frequency Raman scattering and inelastic neutron scattering of amorphous polybutadiene shows that the light-vibration coupling coefficient is linearly frequency dependent. This agrees with earlier findings and we show here that it can be interpreted employing two different correlation lengths for the angular and radial correlations, under plausible approximations.
