【Abstract】 Optical absorption method has been employed to study the thermodynamic pro-perties of C60 molecules. By measuring the transmissivity of C60 vapor, we obtained the dependence of vapor pressure on temperature, ranging from 4101℃ to 850℃. In addition, the sublimation heat of C60 was deduced to be 175kJ/mol, and the corru-ption temperature of C60 cage structure to be 850℃.更多还原
