Summary

PHOTON CORRELATION SPECTROSCOPY HAS BEEN USED SUCCESSFULLY FOR THE MEASUREMENT OF THE THERMAL DIFFUSIVITY OF SOME SELECTED BINARY LIQUID MIXTURES. UNDER THE CONDITION, THAT THE DIFFERENCE OF THE REFRACTIVE INDICES OF BOTH PURE COMPONENTS IS SMALLER THAN 5%, THE THERMAL DIFFUSIVITY CAN BE DETERMINED INDEPENDENTLY ON THE DIFFUSION COEFFICIENT. FOR ROOM TEMPERATURE AND ATMOSPHERIC PRESSURE, THE RESULTS FOR BENZENE-TOLUENE, CARBON TETRACHLORIDE-TOLUENE, DECALIN-TOLUENE, AND BROMOBENZENE-TOLUENE SYSTEMS ARE PRESENTED AS FUNCTIONS OF THE WEIGHT FRACTION.
