Several of the physical properties of liquid cis-decalin seem to change at about 55°C. The surface tension-temperature curve for example shows a change in slope at about this temperature. It was thought of interest to study the Raman effect of the two isomers as a function of temperature in order to find out if the scattering power of the two isomers shows different behavior over the temperature range 25°-75°C. It appears that the scattering of trans-decalin remains about the same over this temperature range while the cisisomer shows increased scattering at the higher temperature. Some ideas are expressed that might account for the phenomenon.
