ملخص

We studied the solidification and melting of certain complex scattering substances by laser Raman spectroscopy. We used a modified laser Raman system to study the spectrum of certain long-chain organic substances (paraffin and candlewax) during solidification and melting, and found that there is a significant and discontinuous change in linewidth (by 4-5 times) during these processes. By measuring the linewidth of a certain line during solidification, we show that at a microscopic level, there is a large change in the immediate microscopic environment and damping of the molecular motions. This shows that Raman spectroscopy can be used as a sensitive probe of the change in the immediate environment of the molecular motions in these systems.
