Abstract :
Terahertz (THz) absorption spectra of supramolecular gels ((1R,2R)-1,2-bis(dodecanoylamino)cyclohexane/2-nitrophenyl octyl ether) were measured by Fourier transform far-infrared spectroscopy (FT-FIR). The spectra were measured by changing concentration and temperature of gels. The absorption intensities of the peaks around 8.6 THz show drastic change at the sol-gel transition temperature.
