Abstract :
We present the first systematic study of the terahertz absorption spectra of confined polar liquids in porous catalysts. The spectra of liquid loaded MCM-41 are acquired using THz time domain spectroscopy over the frequency range of 0.5 - 2.5 THz. The spectra are also compared against bulk liquids to determine the effects of confinement.
