摘要
The temperature dependence of the Rayleigh ratio for benzene was studied for the purpose of comparing various reported values obtained at different temperatures with each other. Light-scattering photometers were calibrated with benzene purified by a preparative gas chromatograph by using a value of the Rayleigh ratio for benzene of R//9//0 equals 46. 5 multiplied by 10** minus **6 cm** minus **1. In order to verify the validity of the calibrations, molecular weight determinations were run on three standard substances: egg white lysozyme, raffinose, and sucrose. The temperature of benzene is directly measured by inserting the sensor of a thermistor thermometer into the benzene within the cell.
