✦ Synopsis

Rotational correlation functions and rotational relaxation times of cyclohexane in porous sol-gel glass were obtained by Raman spectroscopy at temperatures ranging from 173 to 323 K. Three sets of sol-gel glass of diameters 29, 54 and 220 A were studied.

The effects of physical confinement on the rotational motion were observed and related lo pore diameters. The experimental results were compared with computer simulation data.
