Ultrafast optical Kerr effect (OKE) spectroscopy was used to make a quantitative comparison of the intermolecular dynamics of bulk and confined benzene. Room-temperature reduced spectral densities (RSDs) of benzene in nanoporous (27-73 Å) sol-gel glasses bear striking similarities to RSDs of bulk benzene at lower temperatures (270-290K). Upon comparing the RSD shapes, a distinct correlation between the radius of nanopores and temperature of the bulk emerges. These reuslts suggest that confinement significantly impacts physical properties of liquids in ways that limit the kinetic energy of the system. Further experiments are proposed to study these effects in other liquids.
