| Abstract: | Temperature-dependent Fourier transform Raman (FT-Raman) spectra were measured in the temperature range between 30 to 120 degrees C for the azobenzene-containing long chain fatty acid 8A5H in the solid state. Generalized two-dimensional (2D) correlation was applied to calculate temperature-dependent synchronous and asynchronous Raman spectra in order to investigate the sequence of the reorientions arising from the different transient moments associated with molecular vibrations induced by temperature. |
