Ultraviolet-visible absorption spectrum of C60 vapor and determination of the C60 vaporization enthalpy

Abstract
Ultraviolet‐visible absorption spectroscopic studies of C60 vapor were carried out in the temperature range 400 °C–720 °C. The enthalpy of sublimation (180±10 kJ/mol) was obtained through the use of the Clausius–Clapeyron equation.
